摘要
针对已选择的均质土坝方案,根据地貌、地质、泄水建筑物泄洪规模及泄洪建筑物选型原则,对梁河水库工程泄水建筑物型式拟定两种方案,即河岸式侧槽溢洪道和泄洪洞联合泄洪方案、竖井式溢洪道和泄洪洞合二为一相互结合泄洪方案。从地质条件、建筑物布置、施工条件、环境保护、工程投资等方面进行比选,工程泄洪建筑物方案选定为竖井式溢洪道和泄洪洞合二为一泄洪方案,该种布置形式在国内没有工程先例,可为今后类似工程提供设计经验。
According to the selected homogeneous earth dam scheme,according to the geomorphology,geology,the scale of the discharge structure and the selection principle of the discharge structure,two schemes are drawn up for the type of the discharge structure of the Lianghe Reservoir project,namely the river bank side channel spillway The combined flood discharge plan with the spillway tunnel,the shaft spillway and the flood discharge tunnel are combined into one combined flood discharge plan.From the aspects of geological conditions,building layout,construction conditions,environmental protection,project investment,etc.,the project flood discharge building scheme is selected as a combination of shaft spillway and spillway tunnel as a flood discharge scheme.This type of layout is not available in China Engineering precedents can provide design experience for similar projects in the future.
