摘要
为保障八峰水库科学、合理选定设计参数,本文针对坝址处的水文地质条件进行分析,以期为类似水利工程前期勘测设计提供参考。选定溪口水文站作参证站,推算参证站多年平均径流量,利用降雨径流关系推算坝址处多年平均流量。工程区属中低山丘陵地貌,应按Ⅶ度抗震设防,库盆多由凝灰熔岩组成,局部为第四系坡残积层覆盖。压水试验表面,相对隔水层埋深:右岸6~20m,左岸5~17m,河床约1m。
In the paper, the hydrogeological conditions of dam site are analyzed in order to ensure scientific and reasonable selection of design parameters in Bafeng Reservoir, thereby providing reference for pro-phase survey design of similar water conservancy projects. Xikou Hydrologic Station is selected as a benchmark station for calculating average runoff of the benchmark station for many years. The rainfall runoff relationship is utilized for calculating the average runoff of the dam site for many years. The engineering area belongs to medium and low mountain hill landfmxn, Degree VII seismic fortification should be adopted. The reservoir basin is mostly composed of tuff lava. It is locally covered by quaternary eluvial slope lamination. The relative aquiclude buried depth on water pressure test surface： 6 -20m on the right bank, 5 - 17m on the left bank, and about lm for the riverbed.
