摘要
为合理、有效地确定强风化云母石英片岩的岩体力学参数,在工程经验类比法的前提下,以现场原位试验为手段,研究以霍克-布朗强度准则为基础的经验公式法获取参数的可行性。结果表明:一般边坡工程采用经验公式法确定参数是可行的,对于重要边坡工程则应以现场原位试验为主确定参数,从而为获得软弱岩体力学强度参数提供一条可靠途径。
In order to determine the mechanical parameters of rock mass on strong weathered mica-quartz schist reasonably and efficiently,under the premise of engineering experience analogy method,as a means to test in situ,the feasibility to obtain the parameters was studied by the Hoek-Brown strength criterion based on the experience formula method.The results show that the empirical formula method to determine the parameters for the general slope engineering is feasible,the in-situ-test should be done to determine parameters for the important slope engineering.So a reliable way to obtain the weak rock mass mechanical strength parameters can be found.8 tabs,7 figs,9 refs.
