Abstract: Xianlin new campus of Nanjing University is located in Xianlin district in Nanjing, where karst development is widespread. According to in-advance exploration, field investigation, field static load test and measured data of engineering, the key points of in-advance exploration and characteristics of karst were summarized and the reasonable value of karst cave roof thickness was discussed. Design of foundation for the new campus in karst area was introduced, including application of a variety of foundation types in karst area.

Keywords: karst; cave filling; cave roof thickness; CFG pile; cast-in-place pile; pipe pile
