【摘要】 通过分析两次灌浆试验中的单位耗灰量、岩体质量、波速变化、地面抬动及岩体应力状态之间的关系,提出异常高的耗灰量是坝址岩体质量差且发生松动的必然结果,进一步论证了坝址区岩体发生了大规模松动的客观事实。更多还原

【Abstract】 The cement consumption per meter,quality of rock mass,wave velocity,land upheaval,stress status of rock mass,and the relationship among them during and after two grouting tests are discussed in the paper. The rather poor quality of relaxed rockmass results in more cement consumption in grouting test. It is certified further that the rockmass in dam site loosened extensively.更多还原
