| 摘 要： | 分析单试件法测定岩石内聚力c和内摩擦角φ产生误差的原因,提出一种对单试件法各级围压下获得的三轴试验强度的修正方法。用泥岩试件分别在常规多试件和单试件法下的试验结果验证两种方法测定内聚力c和内摩擦角φ存在的差异,以及修正方法的有效性。

| Abstract: | The erroneous reason of determining rock cohesion and the angle of internal friction by single specimen method was analyzed.And the revised method of triaxial strength determined by single specimen method under different lateral presses was proposed.The difference between the two methods to determine the cohesion and the angle of internal friction separately,as well as the validity of the revised method,was confirmed with the mudstone test result using the conventional multi-specimen method and the single s... |
