摘要
积石峡水电站坝址区具备修筑混凝土拱坝和混凝土面板堆石坝的条件,但两种坝型对坝基和坝肩岩体条件(尤其软弱夹层)的要求和适应性有本质差别。积石峡水电站坝型选择起控制作用的地质因素是岩体中软弱夹层的空间分布规律及其工程特性。对积石峡水电站坝址区岩体中软弱夹层特征进行分析,为最终确定合理可行的坝型提供了坚实可靠的地质依据。
The terrain condition in Jishixia dam site is suitable for the construction of concrete arch dam and concrete face rockfill dam. Because the requirements and compatibility of two types of dam have essential distinction to the rock mass conditions in dam foundation and abutment, especially the weak intercalated layer, the geological factors which deciding dam type selection of Jishixia are the spatial distribution and engineering properties of weak intercalated layer in dam site area. The properties of weak intercalated layer are analyzed and it provides a scientific and reliable geological basis to dam type selection.
