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 reasonably and effectively determine the rock mechanics parameters of strong weathered mica quartz schist, under the premise of engineering experience analogy method, the in situ experiment was taken as a means to study the empirical formula method based on Hawk-Brown strength criterion Feasibility. The results show that it is feasible to determine the parameters by the empirical formula method in the general slope engineering. For the important slope engineering, the parameters should be determined mainly by the in situ test in the field, so as to provide a reliable way to obtain the mechanical strength parameters of the weak rock mass.
