某水库枢纽大坝工程坝型比选分析

Comparison and Selection of Dam Type of a Reservoir Hub Dam Project

坝型比选是水库枢纽工程建设规划文件的重要技术环节,对水库工程建设的质量、安全和效率具有重大的工程意义。为此,结合交广水库枢纽大坝工程坝型比选展开分析研究。结果表明,认识工程概况,在已经科学确定的坝址位置,通过坝型适应性分析,确定交广水库可采用沥青混凝土心墙土石坝和混凝土面板堆石坝两种坝型,围绕地形地质、枢纽布置及防渗体可靠性、筑坝材料、工程量及投资、施工技术及条件等多方面因素,经坝线内坝型综合比较,优先沥青混凝土心墙坝方案,确定沥青混凝土心墙坝为最优坝型。可为类似水库枢纽大坝工程坝型比选研究提供借鉴参考。

Dam type selection is an important technical link in the construction planning document of reservoir hub project,which has great engineering significance to the quality,safety and efficiency of reservoir project construction.Therefore,the comparison of dam type of Jiaouang Reservoir Dam project is studied.The general situation of the project is undertood.On the basis of scientifically determined dam site location,through the adaptability analysis of dam type,it is determined that two dam types of asphalt concrete core-wall earth-rock dam and concrete face rockfill dam can be used in Jiaoguang reservoir.Based on various factors such as terrain and geology,hub layout and seepage body reliability,dam building materials,quantity and investment,construction technology and conditions,various factors,through the dam line dam type comprehensive comparison,priority asphalt concrete core dam scheme,asphalt concrete core wall dam is determined as the optimal dam type.It can provide reference for the comparison of dam type in similar reservoir hub dam projects.
