广西威后水电站高拱坝主要工程地质问题

Main engineering geological problems in high arch dam of Weihou hydropower station

文中通过对广西威后水电站高拱坝主要工程地质条件分析和初步研究,针对影响工程实施的几个关键工程地质问题,如地基出露砂泥岩组合、坝肩岩体结构、岩体试验参数选取、地质结构面与拱端推力相互作用、拱座稳定等,提出了合理的建议参数和解决办法,从而使工程得以顺利进行。

Through analyzing the main engineering geological conditions in the high arch dam of Weihou hydropower station, the reasonable parameters and solutions of the key problems such as sandstone and mudstone combination outcrop to the ground, dam abutment rock structure, test parameters selection, interaction of geological structure surface and thrust at Springer, arch support stability are proposed and the project could proceed smoothly.
