内支撑基坑支护体系施工过程的监测及分析

Inner support bracing system for foundation pit construction process monitoring and analysis

摘要:

河南省人民医院新建病房楼基坑采用两道钢筋混凝土内支撑。通过基坑支护桩深层水平位移、支撑轴力、地面沉降、周边建筑物沉降的监测，对各工况下的监测结果进行了分析，找出了各工况对基坑变形的影响因素及规律性，得到一些有益结论，为以后类似工程施工提供经验与借鉴作用。

Abstract:

The internal bracing with two reinforced concrete lines was used in the foundation pit of a new ward building in Henan Province. The monitoring was made on the deep horizontal displacement of foundation pit retaining pile, strut axial force, ground subsidence and the settlement of surrounding buildings, the monitoring results under all the conditions were analyzed to find out the factors affecting the deformation of foundation pit and the regularity under different conditions, some instructive conclusions are obtained, which could be the reference to the similar engineering construction.
