谈岩溶地质对桩基础施工的影响与应对措施

Introduction to Karst Geological Effects on Pile Foundation Construction and Counter Measures

我国是地貌非常复杂的国家,分布有大量的岩溶地貌,而这些岩溶地貌的地质情况复杂、不可控因素较多,导致地基基础施工时极易造成塌孔、埋钻等问题,形成质量安全事故。桩基础施工是保证岩溶地区工程质量最重要的环节,所以要提高对桩基础施工的前期地质条件勘测,根据项目地质实际情况制定科学合理的施工计划。论文对岩溶地区项目桩基础施工的影响和施工中常见的问题及相应处理措施进行详细阐述。

China is a very complex landform country, distribution of a large number ofkarst landform, geological conditions and more complex, these karst uncontrollable factors, resulting in foundation construction prone to problems caused by the hole collapse and burying, the formation of quality and safety accidents. The construction of pile foundation is the most important link to ensure the quality of Engineering in karst area. Therefore, it is necessary to improve the preliminary geological conditions for the construction of the pile foundation, and formulate a scientific and reasonable construction plan according to the actual conditions of the project. In this paper, the influence of pile foundation construction in karst area, the common problems in construction and corresponding treatment measures are expounded.
