摘　　要：针对船闸工程施工过程中遇到地质突变的问题,结合工程实例进行分析和深入研究。对处理机理进行分析,地质突变中地基承载力不足可通过优化上部结构和提高地基承载力两个方面来解决;经多方案比选分析,确定地基浅换填加空箱墙体为推荐方案,并对其荷载及位移等进行计算。结果表明,该方案可通过内部填料调整结构自身重力和重心,以灵活适应较广泛的地基情况。In view of sudden geological change during the ship lock construction,this paper carries out the analysis and in-depth study combining with the engineering example.This paper analyzes the solution mechanism,solves the shortage of foundation bearing capacity casued geological catastrophe by optimizing the superstructure and improving the foundation bearing capacity,determines the solution of shallow foundation replacement with empty box wall as the recommended solution through the comparison and analysis of multiple solutions,and calculates the load and displacement of the solution.The results show that the solution can adjust the gravity and center of gravity of the structure by adjusting the internal filler,and can flexibly adapt to a wide range of foundation conditions.
