摘　　要：基坑工程的施工风险预警是保证基坑安全施工的重要工作,但现有的基坑失稳预警思路只是将某个或某些监测点的破坏视为基坑失稳破坏。以保证基坑安全为前提,从基坑监测点安全和整个基坑体系安全两个层面对基坑进行安全预警。基坑监测点安全的预警,利用所建立的基坑监测项目安全预警分级实现;对基坑体系安全稳定的预警,则是通过建立监测数据和整个基坑体系稳定性之间的层次分析框架,并依赖监测项目安全预警分级表实现了对整个基坑安全稳定的定性和定量评价。该预警方法有效地将监测与预警相结合,并将二者的模糊关系转变为清晰量化的数学关系,为有效解决基坑安全预警问题提供了新思路。The construction risk early warning of the deep excavation is an important task to ensure the safe construction of the excavation.However,the existing deep excavation’s early warning idea is based on the failure of one or more monitoring points as the instability of the deep excavation.Using the principles of ensuring the safety of the deep excavation,the safety early warning of the excavation is carried out from the safety of the excavation monitoring points and the safety of the entire excavation system.The early warning for the safety of the deep excavation monitoring points is realized by using the established safety early warning classification.The early warning of the safety and stability of the excavation system is to achieve a qualitative and quantitative evaluation of the safety and stability of the entire system by establishing an Analytic Hierarchy Framework(AHP)between monitoring data and the stability of the entire system throughout the monitoring project safety early warning grading table.The early warning method effectively combines the monitoring and the early warning and transforms the fuzzy relationship between the two into a clear and quantitative mathematical relationship,which provides a new idea to effectively solve the deep excavation safety early warning problem.
