| 摘 要： | 针对百色水利枢纽碾压混凝土重力坝存在的一些不利因素:坝基岩体地质条件复杂,上游面坝踵区存在一定蚀变带岩体,6号坝段坝基有贯穿坝基上下游的破碎带,且坝基岩层之间有岩层节理面并由此产生渗透各向异性,在充分考虑这些不利因素影响的基础上,采用三维有限单元法,对坝基渗流场进行分析计算,综合论证和评价了坝基的渗流场特性,并推选出坝基防渗和排水设施的渗控方案.

| Abstract: | With a certain corroded belt existing in rock mass in the dam heel region of the upstream face and a fracture belt running through the upstream and downstream dam foundation of the No.6 dam section, the geological condition of the rock mass of the gravity dam foundation is complicated. Furthermore, the joint planes between rock strata result in the anisotropic seepage. Based on the full consideration of some disadvantageous factors, the seepage fields around the dam foundation were calculated with the 3-D Finite Element Method. After comprehensive demonstration and evaluation of the characteristics of seepage fields around the dam foundation, the reasonable seepage control schemes were selected for dam foundation and drainage facilities. |
