李家峡拱坝河床11# 、12# 、13# 坝段部分坝基存在断层密集破碎带。设计采用高压挤密灌浆方案,并对灌浆工艺作了适当的修改。经过近3 年初期蓄水的考验,该部位变形与渗漏量都不大,初步表明对该部位进行治理的设计方案是合理的,施工工艺也满足了要求,本文对此予以简单介绍
The dam foundation of the 11th, 12th and 13th dam sections of the Lijiaxia arch dam has some fault-intensive fracture zones. Design using high-pressure grouting program, and the grouting process made the appropriate changes. After nearly 3 years of initial storage of water test, the deformation and leakage of the site are not large, preliminary shows that the design of the site for the design is reasonable, the construction process also meets the requirements of this article to a brief introduction
