摘要
水库的主要功能是拦洪、蓄水,而地下水的分布特征及其与地表水的补给、排泄关系对水库的不透水性密切相关.GOMALZAM水库库容14亿m3,库盆主要由薄层灰岩组成.在河床部位,地下水位埋藏深度27～28m,所以,对其不透水性、防渗措施的必要性和方案的选择等方面的论证至关重要.在对区内基本地质条件、气候条件、水文地质结构及地下水的补给、径流及排泄条件等综合分析的基础上,对悬河的成因进行了初步的探讨,为工程决策提供了依据.
Functions of reservoir are mainly flood control and storage. The distribution characteristics of the groundwater and its relationship with replenishment and discharge of surface water are closely relevant to impermeability of reservoir. GOMAL ZAM reservoir with a total volume of 1.4 billion m^3 is mainly composed of thin bedded limestone,in which the ground water level is 27 to 28 m below river water. Thus, it is vital that impermeability of reservoir, necessity of anti-seepage and schema choice should be studied. Based on comprehensive analysis of basic geological condition, climate condition,hydrogeological texture, as well as replenishment, runoff and discharge condition of groundwater, origin of suspended river was discussed initially to provide reference for project decision.
