拉西瓦高拱坝岩体力学、工程地质研究成果综述

Summary on the Research Achievements of Engineering Geology & Rock Mechanics of Laxiwa High Arch Dam

拉西瓦水电站高拱坝建基岩体工程地质、岩体力学研究是中国水电顾问集团2004年度专题科研成果之一"高混凝土拱坝建基岩体工程地质、岩体力学综合研究"的主要成果,其重点内容为岩体风化、卸荷、岩体质量级别的定量划分、河谷应力场分带、建基岩体主要岩体力学参数研究,坝肩抗滑稳定、开挖后综合检测验证等;在理论探讨、方法实践、预测验证和创新尝试等方面取得了一定成果,具有一定的社会、经济效益。

The research on engineering geology ＆ rock mechanics of the foundation rock mass of Laxiwa High Arch Dam is one of main achievements of “Integrated Study of Engineering Geology ＆ Rock Mechanics of High Concrete Arch Dam Foundation Rock Mass”, one special research achievement made by the China Hydropower Consulting Corporation in 2004. The important contents are weathering and unload of rock mass, quality classification of rock mass, the partition of river valley stress field, main rock mechanics parameter research for dam foundation rock mass, anti-slide stability of dam abutment, integrated examination after excavation, etc.. There are some theoretical discussions, practice and method, the forecasting and validation, and innovation and try in this paper, which has gained certain results and has certain social and economic benefits.
