Abstract: Aiming at the safe thickness of the bridge pile end's support rock mass in karst and mining region, the determination method had been comprehensively probed by a thorough analysis of the distortion characteristics and the destroyed mechanism of rock mass at the end of the bridge pile. A series of economic, reasonable and safety formulas have been proposed; and they are easy to apply in engineering. Finally, the problems such as the formula's using range, notices, influencing factor and the reasonable selection of the safety factor have been discussed.

Key words: karst, destroyed mechanism, pile foundation, safety thickness
