Method of Ground Improvement in Underground Cave caused by Well-Sump Type Pumping

More Information
  • Published Date: May 25, 1995
  • In underground water resource development, using well sump type pumping can cause underground cave-soil piping seepage failure of some soil stratum. In this paper,the method of ground improvement using rammedbulb piles with structural remedies in the foundation and superstructure is presented. At the same time,the diameterof pile bulb and bearig capacity of rammed bulb pile are discussed.
