预制高强钢管混凝土管桩在基坑支护中的应用

Application of Prefabricated High Strength Steel Tube Concrete Pipe Pile in Foundation Pit Supporting

阐述使用预制桩作为基坑支护桩的优点和研究现状,基于基坑排桩支护相关的理论研究,介绍了SC桩的基本特征、接桩方式、主要力学性能等,并计算了C30混凝土灌注桩的500 mm直径SC桩的等代桩径,解决了常用软件中无法输入相关参数的问题。通过工程实例验证,结果表明,采用SC桩进行基坑支护,有施工方便、安全性高的特点。

Expounds the advantages of using precast pile for foundation pit supporting pile and the research status. Based on the theory of pile foundation pit supporting related research. The basic characteristics of sc pile by pile are introduced mainly mechanical properties ,Calculated the c30 concrete piles of 500 mm diameter of sc generation, such as diameter of pile, Solve the commonly used software unable to enter the relevant parameters of the problem. Through the engineering example, Use sc pile for foundation pit supporting, has the characteristics of convenient construction high safety.
