摘要
针对下坝水库坝址区特殊地形地貌和复杂水文地质条件,根据地质分析成果,综合考虑建坝河段、筑坝材料、施工导流及投资等因素,优选工程适宜性较高的C15砼砌毛石重力坝方案。经枢纽整体布置优化调整和计算分析后,合理确定了大坝坝顶高程和结构经济断面。抗滑稳定和应力计算结果表明:优选重力坝方案的坝体结构整体抗滑稳定性和应力等特征指标均满足规范要求,优选方案可行,经济合理。
The dam site area of Xiaba Reservoir has special topography and landform, complicated hydrological and geological conditions. According to the results of geological analysis while taking into account the factors such as dam building river section, dam construction materials, construction diversion and cost, the C 15 concrete rubble masonry gravity darn scheme was selected due to its relatively superior adaptability. Based on general arrangement optimization and calculation of the project, dam crest elevation and economic structure section were determined. The results of anti-sliding stability and stress calculation demonstrate that the stability and stress indexes all meet the requirements of specifications. The selected scheme is feasible with economic rationality.
