摘要
岩体的参数确定一直是岩土工程中的一个重要及困难的问题,将整个工程岩体划分为不同尺寸等级的计算试件,依据室内外基本材料试验成果,采用数值仿真方法依次计算各级别计算试件,最后得到岩体的宏观力学参数,计算结果与实际情况值基本吻合,该计算方法解决了物理试验对岩体参数评价的局限性以及在整体模型计算中参数选取的任意性。
How to decide the parameters of rock mass is an important and complica ted problem in geotechnical engineering. Firstly it should grade the whole rock mass into several computing models. Then we use the numerical simulation to comp ute the models based on the indoor and outdoor experiments that have been done. At last, the macro mechanic parameters were gained and the results are consisten t with practical values. The computing method avoids the limitation of physical experiments when used to evaluate the mechanic parameters of rock mass, and avoi ds the randomness in selecting the parameters of the whole model.
