TLDR
The water supply network is of great importance for a city, and it faces various risks such as leaks and breaks, so its risk level needs to be evaluated regularly, and a new and improved approach is proposed.Abstract:

Failure analysis and treatments of a loess tunnel being constructed in ground fissure area
TL;DR: Based on the collapse of a tunnel in Xi'an Metro Line 3 near a ground fissure, potential causes and corresponding mechanisms were analyzed in this paper , which indicated that hydraulic erosion induced loose pressure and crack-rich soil below the initial support were mainly attributed to be the triggering force of the collapse.

Strength behavior of circular concrete-filled steel tube stub columns under axial compression: A review
TL;DR: In this article , the compressive strength of circular concrete-filled steel tube stub columns (CFST-SCs) is evaluated and the reliability of prediction results under different influencing factors is discussed.
Journal ArticleDOI
Seepage Characteristics in Loess Strata Subjected to Single Point Water Supply
TL;DR: In this paper , a Conical-like cavity was formed near the water source, and the preferential passage of water flow appeared below the cavity, where a two-dimensional seepage diffusion calculation model was established and preliminarily verified by example calculations.

Quantifying Arctic oil spilling event risk by integrating an analytic network process and a fuzzy comprehensive evaluation model
TL;DR: Wang et al. as mentioned in this paper developed a comprehensive risk assessment framework to suppress potential loss caused by an Arctic oil spill event, and quantified the Arcticoil spill event impact with an ensemble framework supported by the analytic network process (ANP) and fuzzy comprehensive evaluation model.

A troubleshooting manual for handling operational problems in water pipe networks
TL;DR: In this article, the authors present some of the most common operational problems in water pipe networks, studied in the water distribution system of Athens, the capital of Greece, which took place from 1995 to 2000, concerning individual pipes of a network with a total length of 7,000 km.
