摘要
阿拉沟水库工程河床坝基断层发育密度较大,断层破碎带中普遍夹断层泥,且结构复杂。理论计算判定其渗透稳定性存在一定的局限性。通过现场渗透试验得出坝基断层渗透破坏的相关参数,并以此为依据提出了坝基断层的处理措施,得到了较好的效果,也为同类工程积累了经验。
For Alagou Reservoir project,the developing density of the riverbed dam foundation fault is larger,while fault gouge is commonly intercalated inside the fracture zone of the fault with a complicated structure,for which there is a certain limitation to judge its seepage stability with theoretical calculation. Through the in-situ seepage test,the relevant parameters of the seepage failure of the dam foundation fault are obtained herein,furthermore,the treatment measures for the fault are proposed on the basis of this;from which not only better effect is got,but the corresponding experiences are also accumulated for the similar project concerned.
