摘要：
The deformation of karst cave-surrounding rock and its roof thickness are the key indicators to evaluate the stability of karst cave foundation. According to engineering characteristics of pile foundation in karst area, Using mechanical analytical method, cavesurrounding rock elasticity theory and Griffith criterion to calculate the safe thickness of Karst cave roof. According to karst cave-surrounding rock unstable and failure conditions, such as groundwater, different pile diameter, different thickness of Karst cave roof. Through comparing and analyzing engineering cases, the results show that the mechanical analytical method to determine the safety thickness of Karst cave roof can not meet the engineering requirements, determine the safe thickness of Karst cave roof Should be based on stability of cavesurrounding rock.
