软土深基坑支护工程设计实例分析

Example Analysis of Support Engineering Design for Deep Foundation in Soft Soil Area

某核电厂地处软土地区,深基坑支护设计方案根据场地地质条件及周边环境选用了放坡、桩锚等综合支护体系,确保了基坑的安全、稳定,为该建筑物结构的施工奠定了基础。经现场监测,基坑变形各项指标均在设计的控制标准之内,证明该综合支护结构方案是成功的、可行的。

A nuclear power plant is located in a soft soil area.According to the geological conditions of the site,the foundation pit supporting scheme is selected according to the geologic site condition and surrounding environment has put the comprehensive supporting system such as slope,spiral-sprayed soil anchor,ensure the safety and stability of foundation pit,laid the foundation for the construction of the structure of the building.By monitoring and deformation indicators are within the control standards of design,it is proved that the comprehensive supporting structure scheme is successful and feasible and can be for similar deep foundation pit in soft soil area provides a good reference for engineering design and demonstration.
