超高拱坝前期勘察工作中的几点体会

Experience in Preliminary Investigation of Super High Arch Dam

结合新疆某高拱坝项目前期地勘工作的经验和教训,总结、归纳了超高拱坝前期地勘工作布置,尤其是平洞布置与岩体试验工作安排需注重的要点,对坝基岩体质量分级、大坝建基面选择、坝基(肩)抗滑稳定分析、坝基防渗控制、边坡稳定分析等高拱坝主要工程地质问题的分析、论证,提出了分析研究的重点方向和基本思路。

Combined with the experience and lessons of geological survey in the early stage of a high arch dam project in Xinjiang,this papersummarizes the key points of geological survey arrangement especially the layout of adit and rock mass test in the early stage of superhigharch dam. It put forward the emphasis and basic ideas in analysis and demonstration of the main geological problems of high archdam,such as quality classification of dam foundation rock mass,selection of dam foundation face,anti-sliding stability of damfoundation(abutment),seepage control of dam foundation,slope stability,etc.
