基于喀斯特地貌的地基处理技术及案例分析

Foundation Treatment Technology and Case Study Based on Karst Landform

喀斯特地貌较为复杂,地基处理难度较大,易导致沉降、坍塌等问题,严重影响工程建设质量。针对这一问题,文中首先分析了喀斯特地貌导致的工程地质问题,结合现阶段地基处理技术,将喀斯特地貌的地基处理技术划分为跨越法、穿越法、加固法、避让法四类,并结合工程实例深入分析了四类地基处理技术的技术要点及适用范围,对类似工程针对喀斯特地貌的地基处理技术选择具有较大参考意义。

Karst landform is relatively complex,and foundation treatment is difficult,which is easy to lead to settlement,collapse and other problems,and seriously affect the quality of project construction.In view of this problem,the paper first analyzes the engineering geological problems caused by karst landforms,and combined with the current foundation treatment technology,divides the foundation treatment technology of karst landforms into four categories:crossing method,crossing method,reinforcement method,and collision avoidance method,and deeply analyzes the technical points and application scope of the four types of foundation treatment technology with engineering examples.The research results have great reference significance for the selection of foundation treatment technology for similar projects aiming at karst landform.
