摘　　要：丰满新建大坝坝基发育有规模大小不一的断层20余条,断层性状及规模不同,导致各坝段工程地质条件差异较大。通过采用不同的处理方式与方法,消除各类地质缺陷的安全隐患,解决坝体抗滑、抗渗和抗变形稳定问题,确保重建大坝安全运行。There are more than 20 faults with different scales developed in the foundation of Fengman new dam.The characteristics and scales of the faults lead to great differences in the engineering geological conditions of each dam section.Different treatment methods and methods are adopted to eliminate the hidden dangers of various geological defects,solve the problems of anti-sliding,anti-permeability and anti-deformation stability of the dam body,and ensure the safe operation of the reconstructed dam.
