摘要:为了保障隧道施工安全,围绕造成隧道施工事故的人为失误风险、隧道支护风险、测量失误风险、隧道结构风险进行系统动力学分析并构建模型,然后设计四种不同实验方案,进行仿真模拟。研究结果表明:隧道施工风险影响效果大小的排序是:人为失误风险>隧道支护风险>测量失误风险>隧道结构风险。
关键词:隧道施工;人为失误;隧道支护;测量失误;隧道结构
Abstract:In order to protect the safety of tunnel construction,the paper mainly focus on tunnel construction accident caused by four risk to carry on system dynamics analysis,including human error risk,tunnel support risk,measurement error risk,tunnel structure risk,constructs the system dynamics model of tunnel construction risk. Through the design of different experimental program,carries out simulate with the help of Vensim software. The results show that human error risk impact on tunnel construction is the largest,followed by tunnel support risks,measurement error risk,and finally the tunnel structure risk.
Keywords:tunnel construction;human error;tunnel support;measurement error;tunnel construction
