金安小区1#、2#地下车库基坑支护

Jin’an Community 1#, 2# Underground Garage Foundation Pit Supporting

本文中桩基工程中采用PHC管桩施工,但是由于PHC管桩抗剪切力较差,在施工过程中如果出现侧向压力时,极易断裂。地下车库的开挖,对前后楼的桩基影响较大,因此采用放坡、土钉+喷锚支护形式对基坑进行支护。

This paper using the construction of PHC pipe pile in foundation engineering, but due to the poor shear resistance of PHC pipe pile, if there is a lateral pressure in the construction process, it is easy to fracture. The excavation of underground garage has the larger influence on the pile foundation of building, so it takes the support pattern of foundation pit support like slope, soil nail and anchor.
