摘要
本文分析了隔河岩河间地块的地质、水文地质条件和岩溶发育规律.据地下水长观资料及石灰岩含水层渗流的非均质各向异性特征,用有限分析法(FAM)反求了岩体的渗透张量。然后对水库不同蓄水位河间地块可能的渗漏量进行了定量计算。计算表明,间地块无穿越分水岭的岩溶管道,不致产生危害性渗漏,只存在溶隙性渗漏,且渗漏量甚小。
This paper analyses the geological, hydrogeoiogical conditions and the law of karst development at Geheyan inter -river land mass. Based of the long -term observation data of groundwater and the non ?uniform . anisotropic seepage characteristics of the limestone aquifers, using back -calculation and finite analysis methed (FAM) , it obtains the seepage tensor of the rock mass ' Then ?the quantitative calculations of the possible amount of seepage for the inter -river land mass at different storage water level of the reservoir ate carried out . The calculation manifests that ?in the inter -river land mass . no karst piping passing through the water parting and unlikely to create dangerous seepage, only the seepage of dissolving fissures exists, and the amount of seepage is very small.
