摘要: 岩体强度是岩体工程设计中一项非常重要的参数。通过岩块获得相应岩体强度参数的经验折减方法往往具体指标难以确定，且与实际出入较大。引入现代模糊数学理论，首先对基于岩块获得岩体强度参数的模糊折减理论方法进行介绍，然后以一处深挖路堑高边坡岩体为例，利用原位岩体质量特征信息，对其强度参数进行了模糊折减实例分析，并与原位试验结果进行了对比验证。

Abstract: Rockmass strength parameter is an important mechanics index in major engineering. Now many empirical rela-tionships for this parameter based on that of rock often occurs index determination difficulty and inaccurate estimating results. Fuzzy discount method for rockmass strength parameter getting from corresponding rock is introduced in this paper, and then, a deep cut slope is selected as a case, basing on rock mass quality characteristic data from in situ investigation, the rockmass strength parameter is predicted by fuzzy evaluation and verified by in field test results.
