This paper introduces the basic situation of the thin mountain ridge on the left bank of Zhangfeng Reservoir,and expounds the design of the slope protection and drainage of the left bank,the design of the grout curtain and drainage curtain on the left bank,and the design of the treatment of Shangbohou landside mass.

The influence on the seepage field of the depth of the grout curtain and cracks in the cut-off wall on the seepage field was analyzed.

The vibration induced by blasting in the vicinity of a dam foundation can induce some adverse effect on the curtain grouting.
