薛家沟水库溢洪道综合评价研究

Research on the Comprehensive Evaluation of the Spillway of Xuejiagou Reservoir

溢洪道作为水库枢纽重要的组成部分,承担着泄洪任务。以薛家沟水库溢洪道为研究对象,参照相关规范的要求,通过现场调查、地质勘探,结合水力学、结构力学计算,对溢洪道外观完整性、泄流能力、边墙高度、混凝土强度分析和挡墙稳定计算等进行了全面复核。结果表明,薛家沟溢洪道防洪评价为A级,渗流、结构稳定评价均为B级,为水库大坝评价提供了依据,也可为后期运行管理提供指导。

As an important component of the reservoir hub,the spillway undertakes the task of flood discharge.Taking the spillway of Xuejiagou Reservoir as the research object,referring to the requirements of relevant specifications,a comprehensive review was conducted on the appearance integrity,discharge capacity,side wall height,concrete strength analysis,and retaining wall stability calculation of the spillway through on-site investigation,geological exploration,and hydraulic and structural mechanics calculations.The results show that the flood control evaluation of Xuejiagou spillway is Class A,and the seepage and structural stability evaluations are both Class B.This provides a basis for the evaluation of reservoir dams and can also provide guidance for later operation and management.
