| Abstract: | The karst ditch and groove bedding plane under the base of a mountain dam are developed with large scale,most of them are filled with clay and influenced by serious transfusion.Considering the special geologic condition,engineers prolong the washing time of drilling hole,increase the pressure in water resisting test and cement grout pressure,use cement grout method of dense filling,which made remarkable achievement in water resisting. |
