摘要
拉西瓦水电站坝型为双曲薄拱坝,坝基及坝肩主要岩体为印支期粗粒花岗岩,对其进行了大量室内和现场岩体力学试验,全面系统地对试验成果进行数理统计和计算分析研究,获得了建基岩体的变形特征、抗剪强度及岩体的分类。提出了对岩体力学试验方法的改进措施及力学参数选取方法的建议。
Laxiwa project is of thin double - curvature arch dam and its main rock mass is coarse - grained granite in Indosinian epoch at dam foundation and abutments. Thus, a large amount of indoor and in situ rock mechanics tests were carried out, and mathematical statistics analysis and computational analysis of test results were fully and systematically made to achieve deformation behaviour and shear strength of the foundation rock mass as well as rock mass classification. Improvement of rock mechanics methods and selection of mechanics parameters are presented.
