Abstract

Safety risks are complicated in the metro construction, so the identification and control of the risk factors as well as the mitigation of coupling effect of risk events are the important ways to improve the safety performance of the deep foundation pit construction project. The purpose of this paper is to identify the risk sources, figure out the risk propagation path towards accident by establishing the relationships between risk factors and safety incidents (accidents and near-miss incidents). Firstly, a new concept of multi-level risk network based on accident is proposed to describe the complexity of risk relationships in the deep foundation pit construction. Then the critical variables and risk propagation paths are identified with the help of the proposed model, appropriate suggestions are given to similar projects.
