多元信息预警系统在头道穴隧道施工过程中的安全评价方法研究

Tunneling Safety Evaluation Method Based on Multi-information Warning System

为了解决一般安全评价方法单一性、滞后性以及易受人为主观影响的问题,借助多元信息预警系统实测资料,分析了以往公路隧道施工事故原因,在对传统安全评价方法研究的基础上,结合多元信息预警系统工作机制以及在头道穴隧道施工中的应用,提出了一种隧道施工过程的安全评价方法。随着多元信息预警系统在隧道施工过程中的自动采集和监测,构建的评价方法可以将复杂的风险因素及时转化为直观的安全评价结果,同时能够指出具体风险源,最大限度地保障隧道施工安全。

The result of the conventional tunneling safety evaluation system may be incomprehensive, not in time and may be influenced by subjective factors. In the paper, the causes for the accidents during the construction of highway tunnels are analyzed on basis of the data measured by the multi-information warning system; a new tunneling safety evaluation method is proposed on basis of the mechanism of the multi-information warning system and the application of the warning system in the construction of Toudaoxue tunnel. Due to the automatic data acquisition and monitoring function of the muhi-information warning system, the complex risk factors can be converted into definite safety evaluation results by means of the tunneling safety evaluation method established, the specific risk sources can be determined and the tunneling safety can be guaranteed as far as possible.
