公路工程中自锚式悬索桥风险评估关键技术研究

摘要

采用概率风险及改进德菲尔法对某一级公路一座自锚式悬索桥运营期间地震作用下结构风险进行了评估，说明了风险评估关键技术在桥梁工程中的应用技术，为工程的设计与施工提供参考。%The paper adopts the probability risk and improved Delphi method to evaluate the structural risks of the self-anchored suspension bridge under the seismic effect during its operation period,and indicates the application of the risk assessment key technique in bridge projects, so as to provide some reference for the design and construction of the projects.
