摘　　要：不同支护形式在同一基坑中组合使用,能够更有针对性的处理某些周边环境差别较大或土质条件复杂的基坑项目。但不同支护形式交界位置的过渡段为整个基坑的薄弱点,需进行加强处理,而在设计中容易被忽视。以某基坑工程为例,结合基坑自身特点,充分利用部分位置场地空旷的有利条件,在同一基坑中采用支撑和锚桩两种不同支护形式,达到降低造价、缩短工期的目的,同时对锚桩和支撑过渡位置采取了有针对性的处理措施,消除了安全隐患,为类似工程提供参考。The combined application of different support forms in the same excavation can more specifically handle certain projects with different surroundings around environments or complex geological conditions.However,the transition section at the junction of different support forms is the weak point of the project and needs to be strengthened,but it is easily ignored during the design process.This article takes a certain excavation as an example,combines the characteristics of the excavation itself,makes full use of open space besides the excavation,and adopts strut and anchor in the same excavation,to reach the purpose of saving cost and shortening construction period.At the same time,targeted measures were taken to deal with the transitional positions of anchor and strut to eliminate potential safety hazards and provide a reference for similar projects.
