Abstract: There are a variety of cracks occurred in the lower part of main dam pier, of which some have extended to the surface of overflow dam and developed on. In order to realize the reasons of crack forming the 3-D FEM analysis has been performed, and three different reinforcement schemes are compared on the basis of the analysis. The scheme of sticking steel sheet outer has been carried out finally.

摘要： 陆水水利枢纽主坝闸墩下部出现数量不等的裂缝，部分裂缝已延伸到溢流坝面，并有继续发展的趋势。为了解裂缝形成的原因，本文进行了三维有限元分析，在此基础上，对三种不同加固方案进行分析比较，最后确定外粘钢板加固方案较合理。
