文章摘要：高地應(yīng)力區(qū)大型水電硐室圍巖工程地質(zhì)特征較一般地應(yīng)力狀態(tài)下差異很大,相應(yīng)圍巖分類評價思路及體系應(yīng)有所差異,但目前水電工程圍巖分類法（簡稱HC法）對評價高地應(yīng)力區(qū)尚存在諸多缺陷,造成評價結(jié)果與真實情況存在一定差距。以高地應(yīng)力區(qū)HC法合理應(yīng)用為研究目的,首先,對該方法存在諸多問題全面分析,并提出相應(yīng)修正建議;其次,通過廣泛搜集、整理目前大型水電工程地應(yīng)力狀況資料,對地應(yīng)力分類評價指標(biāo)及標(biāo)準(zhǔn)提出新的建議;而后,針對HC法對高地應(yīng)力區(qū)的評價思路與方法進(jìn)行優(yōu)化,提出相應(yīng)優(yōu)化方法;最后,以在建的猴子巖水電站主廠房為分析實例,采用對比分析方法印證該優(yōu)化方法的適宜性。該研究方法對于推動HC法滿足高地應(yīng)力區(qū)地下硐室圍巖質(zhì)量評價具有一定參考意義。

Abstr：The engineering geological characteristics of the surrounding rock of large hydropower caverns in high geostress areas are very different from those in the normal geostress area. So the rock classification and evaluation system should be different. However,the hydropower classification（HC） method of rock mass for evaluating the rocks in high geostress areas has still many defects,and has caused some deviations between the evaluated results and the real situations. The purpose of this paper is to correct and optimize the HC method in high geostress areas. Firstly,the problems existed in the HC method were analyzed comprehensively,and some appropriate amendments were proposed. Secondly,some new proposals for ground stress evaluation and classification criteria were proposed through extensive collecting and collating of the information of high geostress of the current large-scale hydropower projects. Then,the evaluation ideas and methods of HC for high geostress areas were optimized systematically and the corresponding methods of optimization were proposed. Finally,the plant of Houziyan hydropower station under construction was analyzed,and the comparative analysis was made to confirm the suitability of this optimization method.
