建筑工程深基坑支护施工关键技术

KEY TECHNOLOGIES FOR DEEP FOUNDATION PIT SUPPORT CONSTRUCTION IN BUILDING ENGINEERING

建筑深基坑工程危险性较大,发生安全事故后,将会造成严重经济损失与人员伤亡,特别是地质复杂基坑,必须做好基坑支护工作,维持基坑稳定性,减少沉降变化。基于此,以深基坑支护施工关键技术的作用为切入点,结合某临床培养基地工程,简要分析工程土壤条件、桩锚支护设计、工程重难点,以此为基础,提出关键技术应用措施,从而为相关工作者提供参考。

The construction of deep foundation pits is highly dangerous,after a safety accident occurs,it will cause serious economic losses and casualties,especially in geological complex foundation pits.It is necessary to do a good job in foundation pit support,maintain foundation pit stability,and reduce settlement changes.Therefore,the article takes the role of key technologies in deep foundation pit support construction as the starting point,combined with a clinical training base project,briefly analyzes the engineering soil conditions,pile anchor support design,and key and difficult points.Based on this,key technology application measures are proposed,providing reference for relevant workers.
