隧道浅埋段冒顶事故与监控量测数据相关性的分析

Tunnel Shallow Segment Roof Collapse Accident and Monitoring Measurement Data Dependency Analysis

本文以某在建高速公路为例,通过对监控量测中拱顶下沉和地表沉降的数据变化分析,成功预测了隧道洞口附近的坍塌冒顶事故,提前发出预警,保证现场了施工人员的安全。通过监控量测结果来预测风险提供了一定的参考价值,对指导工程施工具有一定的借鉴意义。

Taking the highway under construction for an example, it successtully forecasts me tunne~ neat the cave roof collapse accidents and warns in advance to guarantee people who work on the site by data changes analysis of monitoring measurement of crown settlement and ground surface settlement. This pro- vide a valuable reference for risk forecasting by monitoring measurement result and has a certain reference significance to guide the engineering construction.
