基于岩溶复杂地质的高速公路桥梁桩基施工技术研究

Study on Construction Technology of Pile Foundation of Expressway Bridge Based on Complex Karst Geology

面对岩溶复杂地质环境的高速公路桥梁桩施工,较一般地质环境下施工具有更多的质量控制点,文章以实际岩溶复杂地质环境下高速公路桥梁桩基施工工程为背景,首先就岩溶复杂地质环境进行了简介,然后就文章背景工程从工程情况,地质情况以及施工方案三方面进行了概况,进而对工程桩基成孔施工技术展开了详细的分析,最后就工程灌注桩成桩施工技术进行了简要分析,旨在提供一些岩溶复杂地质环境下高速公路桥梁桩基施工的技术参考,提升施工质量。

The expressway bridge pile construction in complex Karst geological environment, has more quality control points compared with that in the general geological environment. Based on the background of the expressway bridge pile foundation construction in complex Karst geological environment, firstly, this paper introduces complex Karst geological environment, and then on the background of the project,from three aspects of the engineering situation, geological conditions and construction plan, makes a general situation, and carries out a detailed analysis of the pile foundation hole construction technology. Finally, the paper briefly analyzes the pile construction technology of bored pile, aiming to provide some references for the expressway bridge pile foundation construction technology under the complex geological environment of Karst, and improve the quality of construction.
