In the construction and operation process of high-way in karst region, it is easy to form the ground subsidence of pile foundation, so the pile must determine the thickness of to make sure the safety of pile foundation. This paper through the high-density electrical method and dril ing prospecting of karst area Pingzan (Pingshan, Zanhuang) Expressway example, il u-strates the high-density electrical method combined with mis-ering Is an effective exploration method in karst area highway survey.
