摘要
为尽可以减少建筑基坑无支撑暴露时间,在分析了钢筋混凝土支撑与钢支撑特点的基础上,总结了钢筋混凝土支撑体系基坑变形控制的要点,为了克服钢筋混凝土支撑体系的弱点,践行限时施作钢筋混凝土支撑的方法。经过实际工程案例验证,该方法具有较好的基坑变形控制效果,可在建筑基坑施工中推广。
To reduce the exposure time of the foundation pit without support as much as possible,based on the analysis of the characteristics of reinforced concrete support and steel support,the key points of deformation control of the foundation pit with reinforced concrete support system are summarized.In order to overcome the weakness of reinforced concrete support system,the method of time-limited reinforced concrete support is practiced.The actual engineering case verified that the method has good foundation pit deformation control effect,which can be popularized in the construction of foundation pit.
