深厚软土地区基坑支护、桩基及开挖分析

Analysis of Foundation Pit Supporting, Pile Foundation and Excavation in Deep Soft Soil Area

深厚软土地区土方开挖过程中容易引起桩基倾斜,应采用合适的开挖方式进行挖土。同时,基坑支护应选用合适体系,设计应预留一定的安全富裕度。现场的施工总平面布置应跟基坑支护设计和开挖流线相匹配,保障坑内桩基和坑外周边环境的安全。

Pile foundation inclination is easy to occur during earthwork excavation in deep soft soil area,so appropriate excavation method should be adopted to excavate soil.At the same time,appropriate system should be selected for foundation pit support and a certain degree of safety and richness should be reserved in the design.The general layout of the construction site should be consistent with the foundation pit support design and excavation flow line to ensure the safety of pile foundation in the pit and the surrounding environment outside the pit.
