| 摘 要： | 对湖北省西部某高速公路宜昌—恩施段主要岩体结构面(层面)的抗剪强度参数进行了较系统的试验研究,包括岩体结构面的野外地质调查、岩体结构面原位直剪试验、结构面室内模拟试验及岩体力学参数估值等。通过对各种试验数据进行整理、分析和对比,得到了岩体结构面强度参数。最后在岩体工程分类的基础上,利用Hoek-Brown经验方法对各类岩体结构面强度参数进行了估算。综合以上多种数据,并考虑岩体结构面所处具体地质条件,提出了各类岩体结构面强度参数建议值。

| Abstract: | The shear strength parameters of rock mass and structural surface (bedding plane) of a certain freeway of Yichang-En'shi segment in Hubei province are studied. The main contents includes: the brief field investigation of rock mass and weak structural surface, in-situ shear testing of weak structural surface, indoor simulation testing between rock and structural surface, the experiential method estimating parameters of rock mechanics. On the basis of analyzing and balancing of the large amount of data obtained from testing all kinds of advising values of shear strength parameters of weak structural surface calculated, and considering concretely geological condition of engineering rockmass, This paper provides a universal and feasible method. |
