坝基岩体要求的条件是:<1>能安全地承受来自坝体传递的力;<2>对于水库的渗流应是不透水的。在这里谈谈关于水库渗漏(或渗透特性)与大坝地质的关系。1、由于地形条件(山脊单薄)所造成的渗漏近来,在大坝规划时,由于坝址条件的限制,而采用超过该坝址地形地质条件所容许的高度,而且这种情况在不断增加,如图1所 The conditions required for the dam foundation rock mass are: <1> the force transmitted from the dam body can be safely borne; <2> the seepage flow to the reservoir should be impermeable. Here to talk about the relationship between reservoir seepage (or permeability characteristics) and dam geology. 1. Leakage due to topographical conditions (thin ridge) Recently, the dam height has been increased due to the restriction of the dam site due to the restriction of the dam site conditions, and this situation is constantly increasing , As shown in Figure 1
