What is the standard of practice for cross passage tunnels?
Best insight from top research papers
The standard of practice for cross passage tunnels involves the use of numerical simulation and field measurement to study construction stability and control structural deformation. The "cross passage parallel shaft construction" method is advantageous in controlling the stress distribution and deformation of the original shaft structures . Comprehensive reinforcement measures of subgrade, rail, and hole are effective in controlling surface settlement and track deformation within standard values . Complicated modeling is used to approximate cross passage behavior and design necessary support structures, with validation through field data from construction projects being limited . Excavation of cross passages presents different challenges depending on subsurface conditions, and traditional methods are typically used with limited access . The procedure for construction involves excavating an underground transport tunnel and making a bypass tunnel connecting the two pipes using a tunnel boring machine .

What are the benefits of using standards to design roads?4 answersUsing standards to design roads has several benefits. Firstly, higher geometric standards have been shown to improve road safety, with freeways being the safest form of road. Secondly, performance-based standards offer opportunities to increase productivity and flexibility in the road transport industry, while still maintaining safety and protecting road infrastructure. Additionally, design standards for streets and roads are crucial for ensuring traffic safety in large cities. Furthermore, the use of standards in road design can lead to cost-effectiveness and predictability in terms of user costs. Overall, implementing standards in road design can improve safety, increase productivity, and provide economic benefits.
What are the challenges to using standards to design roads?5 answersThe challenges to using standards to design roads include the need for flexibility in design to consider specific site needs and community values, rather than relying on centralized, standardized solutions. Additionally, the current design standards may not always be met due to local conditions, leading to the need for design exceptions or upgrades. Another challenge is the lack of national standards for low-volume roads, resulting in nonuniform treatment and the need to reduce national standards to meet economic constraints. These challenges highlight the importance of considering environmental, cultural, and preservation aspects in road design, as well as balancing safety and construction costs. A paradigm shift is needed to move towards more progressive approaches informed by research-based evidence.
What are the standard care practices for drug addiction?3 answersStandard care practices for drug addiction include multidisciplinary treatment teams, pharmacotherapy, and quality nursing care. Multidisciplinary treatment teams offer updated treatment and care for persons with drug addiction (PDDs). Pharmacotherapy, along with supportive psychosocial interventions, is an effective standard treatment for managing psychotic symptoms in PDDs. Quality nursing care is essential for improving the quality of life, health status, and continued abuse-free status of PDDs. Consensually established principles of clinical conduct, known as practice guidelines, have been developed by various organizations such as the American Psychiatric Association, American Psychological Association, and American Society of Addiction Medicine. These guidelines aim to provide standardized approaches for the treatment of addictive disorders. However, objective descriptions of what constitutes standard practice in community-based drug abuse treatment are lacking. Efforts to bridge the gap between research and practice in drug abuse treatment have shown only moderate success.
What are the seismic behaviour of cross vaults?5 answersCross vaults are structural components that are vulnerable to seismic actions due to the horizontal thrust they impose on supporting vertical elements. Experimental tests have shown that cross vaults made of brickwork and supported by stone masonry walls exhibit vulnerability in their original state. However, strengthening techniques such as grouting of piers, arrangement of struts/ties at the base of the vault, and vertical prestressing of the masonry piers can improve their behavior in terms of sustained maximum base acceleration, deformations, and observed damage. The seismic response of cross masonry vaults is influenced by factors such as brick patterns and boundary conditions. Different brick arrangements and boundary conditions can significantly affect the stiffness, ductility, and global capacity of the vaults. Experimental campaigns on reduced-scale 3D printed vaults have provided insights into their seismic behavior, including damage, collapse mechanisms, displacements, and in-plane distortion. Hybrid numerical models combining finite and discrete element methods have been used to accurately predict the behavior of masonry cross vaults under quasi-static and seismic actions, considering factors such as anisotropic damage, large deformations, and real cracking patterns. The seismic response of brick groin vaults, which are commonly found in monumental buildings, has been investigated through static and dynamic nonlinear numerical analyses, considering boundary conditions, loadings, and the role of infill and seismic input amplification.
What are the standards in railway?2 answersStandards in the railway industry are essential for ensuring safety, reliability, and cost-effectiveness. The railway command structure in the UK has transitioned from a monolithic system to fragmented and autonomous businesses, making a robust standards regime critical. Railway Group Standards, developed through an open consultative process, represent the common core standards that all parties involved must observe. These high-level performance-based standards outline the requirements that individual companies need to meet, and they may create additional related documents, such as specifications and procedures. Noise standards in railway environmental impact assessments should prioritize noise discharge standards and consider the type of railway and its noise characteristics for improved scientific character and feasibility. Regulations and standards play a crucial role in public rail transportation systems, affecting capital and operation costs, and regulatory entities and standard-setting entities are involved in their development and implementation. A railway communication module based on HomePlugAV standards has been developed, providing network interfaces, real-time monitoring, and high interference resistance.
WHAT Is standard?1 answersA standard is an established norm or requirement list that can be used to shape and regulate practices. It can be a technical solution that is defined, tested, and repeatable in industrial settings. Standards are often viewed as external and objective, standing opposed to human subjectivity. However, there is a growing recognition of the interplay between standards and subjectivity, acknowledging their role in shaping practices and affecting economies. Standardization is a process of developing uniform criteria and integrating standards across diverse areas. Standards are created to make processes work more easily and economically, allowing for cooperation among disassociated individuals. Different measures of central tendency can be derived from different metrics, and the choice of the formula for standard deviation is based on the shortest distance in the standard metric.
