塔勒克河与新疆干旱区许多河流一样,也具有随流程的增加地表水量急剧损失的特点,但原因各有不同。在塔勒克引水工程闸址比选的各个阶段,上下闸址间集中渗漏问题一直倍受关注,此问题的焦点是下闸址在枯水期有多少水可引。本文通过调查实例介绍了此类问题的调查评价思路,主要采用常规水文工程地质调查方法取得调查结果,采用地质分析法、水文水均衡分析法推断得出渗漏通道位置和渗漏量,提出适宜布置闸址的河段和可引水量的结论。
Like many rivers in the arid region of Xinjiang, the Talek River also has the characteristic of drastic loss of surface water as the process increases, but for different reasons. In all stages of the TARL diversion project site selection and comparison, the problem of concentrated leakage between the upper and lower gateways has drawn much attention. The focus of this issue is how much water can be diverted by the lower gate site during the dry season. In this paper, the investigation and evaluation ideas of such problems are introduced through the investigation examples. The survey results are obtained mainly by the conventional hydrological engineering geological survey method. The location and leakage of the seepage channel are deduced by geologic analysis method and hydrology-water equilibrium analysis method, Layout of the site of the river and the amount of water can be concluded.
