摘　　要：为提高城市地铁车站洞桩法施工过程中的安全性,提前了解施工期间存在的安全隐患并做好安全防护措施,以北京新建王府井地铁车站项目为依托,详细介绍了层次分析法与专家调查法结合的风险评价方法原理,并提出一个适用于王府井车站洞桩法施工的风险评价模型。然后,通过建立的风险判断矩阵计算出各分区的权重值并进行排序。最后通过专家打分结合隶属函数公式对风险因素进行排序。结果表明:既有车站工程、车站自身主体工程为最高级别风险,不良地层风险、设计变更风险、孔位偏移风险等对施工过程的影响较小,基本上可忽略不计。该方法的研究结果为工程管理人员确定风险因素提供了理论依据,为地铁车站建设项目的顺利进行奠定了基础。In order to improve the safety in the construction process of the tunnel pile method in the city subway station,the hidden danger existing in the construction period should be understood in advance and the safety protection measures should be taken.Based on the New Wangfujing Subway Station Project in Beijing,this paper introduces the principle of risk assessment method combining analytic hierarchy process and expert investigation method in detail,and puts forward a risk assessment model suitable for the construction of tunnel pile method in Wangfujing Station.Then,the weight value of each partition is calculated and sorted through the established risk judgment matrix.Finally,the risk factors were ranked by expert rating and membership function formula.The results show that:existing station engineering and the main project of the station itself are the highest level risks.The adverse formation risk,design change risk and hole location deviation risk have little influence on the construction process and can be ignored basically.The research results of this method provide a theoretical basis for engineering managers to determine risk factors and lay a foundation for the smooth progress of subway station construction projects.
