江垭水利枢纽重力坝基础处理设计

Foundation Treatment Design for Gravity Dam of Jiangya Hydro-junction

江垭水利枢纽工程坝址位于岩溶发育地区，软弱夹层、顺河溶隙和承压热水等地质问题将对坝基稳定、渗漏、岩体变形产生影响。本文对坝基处理的设计原则、研究手段、处理措施以及坝基处理后所达到的要求和效果，进行了系统的阐述。

The Jiangya Water Control Project is sited in carst development area. The geological problems,such as weak interbed,solution crack aIong river and confined warm water,etc. affect the dam foundation sta-bility,seepage and rock deformation. The systematic exposition is carried outto design principles,investiga tion means,measures of darn foundation treatment, as well as demands and effects reached after darn founda-tion treatment.
