李家梁水库坝址选择分析

Analysis on Dam Site Selection for Lijialiang Reservoir

李家梁水库工程是一座具有农业灌溉、乡镇和农村供水等综合利用功能的中型水利工程。针对李家梁水库坝址区地质条件复杂情况,综合考虑了地形地貌、地层岩性、地质构造及库区水文条件、水库功能、规模、施工条件与筑坝工程量、移民搬迁、投资等因素后优选了拟建坝址,经比较分析后选择了中坝址方案。李家梁水库坝址的比较选择方法可供同类工程参考。

Lijialiang reservoir is an multipurpose medium- sized water conservancy project for agriculture irrigation,township and rural water supply. Due to complex geological conditions in dam area of Lijialiang reservoir,the proposed dam sites are selected based on topography and geomorphology,formation lithology,geological structure and hydrological conditions in reservoir area,reservoir functions and sizes,construction conditions and dam construction volume,resettlement and cost. Finally,middle dam site scheme is selected by comparative analysis. The comparison selection method for Lijialiang reservoir dam site provides reference to the similar project.
