主　　题：Karst Cave detection Sonar detection Application research 

摘      要：The existence of karst cave at the bottom of bored piles has a great impact on projects under construction and the surrounding *** bored piles require slurry wall protection,the current geophysical exploration method cannot effectively detect the karst cave at the bottom of the piles in the *** with the characteristics of stress wave propagation,the sonar detection method is *** sonar detector can realize the transmission and acquisition of on-site sonar *** method makes full use of the mud conditions of bored cast-in-place piles,and the development of karst caves can be tracked and detected within 10 meters at the pile bottom during the drilling *** has several advantages,including low cost,high speed,and high *** paper verifies the application of sonar detection technology in practical engineering through specific engineering *** research results put forward a new solution for cave exploration in karst areas,especially in liquid environment.
