摘要

某水库工程的双曲拱坝基岩为上软下硬的近水平层状岩体,不同高程的岩体性状差异明显。首先对坝址区主要持力层岩体进行岩体质量分级,其次对薄层灰岩、钙质泥岩夹泥质白云岩进行了抗剪试验与变形试验,试验结果与所在岩层的岩体质量分级及结果相符。最后根据坝基岩体力学特征提出了工程建议。

Abstract

The foundation stratum of a concrete hyperbolic arch dam consists of near horizontal layered rockmass having relative soft layers in the upper abutment. There are obvious differences among rockmass behavior at different elevations. In this research, rockmass quality classification is carried out for the main bearing stratum at dam site, and then direct shear tests and deformation tests are conducted for thin limestone and calcareous mudstone interlayer nuddy dolomite. Test results are in agreement with the results of rockmass quality classification. Some engineering recommendations are also given in the light of dam foundation’s rockmass mechanical characteristics.
