摘要

通过对小湾水电站松弛岩体抗剪特性以及更深入的现场和室内多种试验研究，以更细致深入的评价松弛岩体结构面的变形破坏机理及抗剪强度参数，为后续评价坝基固结灌浆效果以及复核拱坝坝基开挖和地基处理设计方案提供可靠的依据。

Abstract

In order to evaluate more deeply and articularly the deformation and failure mechanism and shear strength parameters of relaxed rock mass structural plane

and to provide reliable evidence for subsequent assessment of consolidation grouting effects of dam foundation and recheck arch dam foundation excavation and design scheme of foundation treatment

the researches on shear resistance of Xiaowan Hydropower Station relaxed rock mass infield and laboratory are carried out.
