摘要/Abstract

摘要： 为识别小直径深层排水隧道盾构施工安全风险,准确评价施工安全风险等级,提出基于危险与可操作性分析(HAZOP)的风险识别方法和基于粗糙集和云模型的风险评价方法。基于HAZOP方法全面识别施工安全风险,并根据粗糙集属性约简理论构建评价指标体系;将粗糙集与云模型结合,构建小直径深层排水隧道盾构施工安全风险评价模型;以东湖深隧工程为例,验证该模型的有效性。结果表明:该模型评价结果与实际情况基本吻合;掘进参数未及时调整、培训及考核不到位、注浆管堵塞、吊装下井设备及其零部件坠落、工程地质和水文地质情况调查不详细是小直径深层排水隧道盾构施工安全风险等级较高的因素,应重点关注并规避。

Abstract: In order to identify construction risk of small-diameter deep drainage tunnel shields and accurately evaluate risk level, a HAZOP-based risk identification method and an evaluation method based on rough sets and cloud models were proposed. Firstly, construction risks were identified comprehensively by using HAZOP and an evaluation index system was established according to attribute reduction theory of rough sets. Then, a risk assessment model for small-diameter tunnel shield construction was established by combining rough sets and cloud model. Finally, the model was verified with deep tunnel project of East Lake as an example. The results show that evaluations of the model are basically consistent with actual situation, and major factors causing high- level construction risks include delayed adjustment of tunneling parameters, deficient training and evaluation, clogged grouting pipes, falling down of hoisting equipment, and unspecific engineering geological and hydrogeological surveys, and they should be checked and avoided.

Key words: small-diameter shield tunnel, deep diainage tunnel, construction safety risk, hazard and operability study (HAZOP), rough sets, cloud model
