摘　　要：针对软土地基上采用桩基处理的水闸在运行后容易因软土固结下沉而导致闸底板下脱空,提出采用冲击映像法对水闸闸基进行脱空检测,通过对田基沙水闸的检测,说明该方法在水闸闸基脱空检测中可取得良好效果,可在类似工程中推广使用。The sluice with pile foundation treatment on soft soil foundation is easy to void under the sluice floor due to the consolidation and subsidence of soft soil after operation.This paper proposes to use the impact image method to detect the sluice foundation.Through the detection of TianjishaSluice,it shows that this method can achieve good results in the detection of the sluice foundation.It is worth popularizing in similar projects.
