摘要
我国地质条件较为复杂,在实施工程时存在一定的阻碍,传统的地质工程施工技术在实际的工程建设中,仍存在一定的问题。因此,本文对复杂地质下的双排桩复合锚杆支护结构施工技术进行研究分析。构建预应力支护桩墙,建立复合支护非线性结构模型,在此基础上,利用组合锚杆形成联合支护层,并使用复合钉锁法实现锚杆支护结构创建。实验结果表明,双排桩复合锚杆支护结构为复杂地质工程建设提供了极大的便利,同时锚杆张拉力值的提升也在一定程度上增加了建筑物的总体坚固性,对复杂地质工程建设具有非常重要的意义。
China's geological conditions are relatively complex,and there are some obstacles in the implementation of the project.The traditional geological engineering construction technology still has some problems in the actual engineering construction.Therefore,the construction technology of double row pile composite bolt support structure under complex geology is studied and analyzed.The prestressed support pile wall is constructed,and the nonlinear structural model of composite support is established.On this basis,the combined anchor rod is used to form the combined support layer,and the composite nail lock method is used to create the anchor rod support structure.The experimental results show that the double row pile composite bolt support structure provides great convenience for the construction of complex geological engineering.At the same time,the increase of bolt tension value also increases the overall firmness of the building to a certain extent,which is of great significance to the construction of complex geological engineering.
