Risk assessment of construction of excavations in areas of rock and soil

摘要

摘要: 随着经济发展以及城市化进程的加快，青岛、大连、重庆等岩石地区城市为改善城市交通状况也陆续展开轨道交通建设。岩石地区不同于软土地区在地铁车站基坑工程施工中受多种不确定因素影响，具有模糊性和随机性。依托青岛地铁三号线某车站基坑工程，运用事故树法对土岩组合地质条件下地铁基坑施工进行风险识别并建立风险评价指标体系。基于层次分析法和模糊集法建立三级模糊综合评判计算模型对该车站基坑施工风险进行评估，计算结果表明该方法合理有效，可为同类工程参考借鉴。

Abstract: With the acceleration of economic development and urbanization, some cities in rock areas, such as Qingdao, Dalian and Chongqing, has launched rail?transit?construction to improve the urban traffic conditions. Different from soft soil areas, construction risk of excavations of subway stations in rock areas is affected by various uncertain factors with random and fuzzy behaviors. Based on the subway station construction of Qingdao Subway Line No. 3 Project, a synthetic evaluation index system for excavation construction risk of subway stations in rock and soil areas is established by analyzing the factors that influence subway station construction with the fault tree method. A model of three-stage fuzzy synthetic evaluation on the basis of analytic hierarchy process and fuzzy method is adopted to assess excavation construction risk of the subway station. The analytical results show that the proposed method is practical and helpful to other similar projects.
