TL;DR: In this paper, the relative performances of braced and tied-back wall systems are compared and key factors in the different performances of the two systems are isolated and the degree of their influence demonstrated.
Abstract: Parametric finite element studies are described that illustrate the relative performances of braced and tied-back wall systems. Key factors in the different performances of the two systems are isolated and the degree of their influence demonstrated. Circumstances are shown where tied-back wall systems perform better than braced wall systems and vice versa. Additionally, the influence of prestress load, wall stiffness, tie-back stiffness, excavation depth, and tie-back spacing on tied-back wall performance are investigated. By judicious choice of these parameters it is shown that the designer can significantly reduce wall movements and soil settlements.

TL;DR: In this paper, the authors investigated the effective stress variations adjacent to a diaphragm wall during construction of a 10-m-deep excavation in stiff fissured clay.
Abstract: The mechanical behavior of many soils such as stiff clays depends on their current effective-stress states and stress history. For improving design and analysis of soil-structure interaction associated with deep excavations in these soils, it is important to understand effective-stress changes around excavations caused by both horizontal and vertical stress relief. In this paper, total and effective-stress variations adjacent to a diaphragm wall during construction of a 10–m-deep excavation in stiff fissured clay are reported and discussed. Interpreted field stress paths are compared with some relevant laboratory triaxial stress path tests, which simulate the horizontal and vertical stress relief in the field at an appropriate stress level. The interpreted field effective-stress paths in front of the wall are found to be similar to laboratory stress paths determined in undrained extension tests. Field stress paths behind the wall do not correspond particularly well with those from laboratory undrained compression tests, except when the stress state approaches active failure. The conventional undrained assumption does not seem to hold for the soil located immediately behind the wall during a relatively rapid excavation in the stiff clay.

TL;DR: In this article, a series of finite element (FE) models to investigate the dynamic behavior of soil arching effect in piled embankment was presented to simplify the problem of time-consuming and difficult to convergence.
Abstract: Most research conducted so far has investigated the soil arching in piled embankment under static loads, knowledge on their dynamic behaviors under transient loads of moving vehicles is rather limited in the literature, especially considering the subsoil consolidation, and therefore it deserves more research attention. This paper presented a series of finite element (FE) models to investigate the dynamic behavior of soil arching effect in piled embankment. At a given load cycle number of 300, since the subsoil was not fully consolidated, ‘Model B’ yielded much smaller results in terms of both the settlement and earth pressure coefficient than ‘Model A’, with the difference of approximately 50%. A three-dimensional (3D) column model with a simplified subsoil consolidation procedure (Model E) was presented to simplify the problem of time-consuming and difficult to convergence. A close agreement was observed between the two models both in terms of the settlement and the earth pressure coefficient of the embankment, and therefore concluded that ‘Model E’ was much more suitable for the simulation of piled embankment under dynamic loads. The parametric study relating to the dynamic load type, velocity and vehicle wheel load showed that the soil arching effect remained valid, but was reduced under dynamic loads, especially when the vehicle wheel load and velocity were relatively large. The dynamic load type was found to have an obvious influence on the soil arching effect, in which the settlement increased by approximately 6% when varying the half-sine load type to the sine load type. As expected, the increased vehicle wheel load and velocity aggravated the dynamic vertical stress and settlement of the piled embankment.
