双排桩在水利工程深基坑支护中的应用

Application of Double-row Piles in Deep Foundation Pit Support of Water Conservancy Project

双排桩结构是新型深基坑支护技术,当基坑无法进行内支撑情况时,其发挥着重要作用。相比于悬臂结构,双排桩结构所支护的深度更大,并且具备良好的刚性和抗弯性,因此在工程现场受限基坑支护中,双排桩具有更加良好的效果,对于双排桩结构的应用需要结合工程现场实际情况进行详细计算,确保应用合理性、安全性。文章以双排桩在水利工程深基坑支护中的应用为题首先概述双排桩,然后分析双排桩结构的计算模型和其优点,最后结合实际案例分析双排桩在水利工程深基坑支护中的应用。

Double-row-pile structure is a new deep foundation pit supporting technology,when the foundation pit can not be supported inside,it plays an important role. Compared with cantilever structure,double-row-pile structure has a largerdepth of support and good rigidity and bending resistance,thus double-row-piles have better effect in the limited foundation pit support. For the application of the double-row-pile structure,it need to be calculated in combination with the practical situation of engineering field in detail,to ensure the application of rationality and security. In this paper,the application of double-row-pile in deep foundation pit support of water conservancy project is given as the topic,firstly,the double-row-pile is summarized,then the calculation model of double-row-pile structure and its advantages are analyzed,and finally,the application of double-row-pile in deep foundation pit support of water conservancy project is analyzed with a practical case.
