摘　　要：桩基础水闸的翼墙邻近及其外侧土体常发生脱空、疏松或扰动等变形现象。在分析某水闸工程特点、土体性质、现场环境条件及探地雷达和地震映像法原理的基础上,开展了综合探测和分析工作。探测结果表明,探地雷达和地震映像法的综合运用能够较有效地圈出土体扰动范围及局部疏松和脱空位置,为相关工程措施提供依据。The soil near and outside the wing wall of pile foundation sluice often deform,such as vacancy, loosen,disturbance,and so on. Comprehensive detection and analysis for one sluice project are carried,on the basis of analysis on its characteristics,soil property and condition,and the principle of ground penetrating radar （ GPR） and seismic image method. The exploring results demonstrate that disturbance range and local loosen and vacancy position of soil can be pointed out using both GPR and seismic image method simultaneously.
