The rock mass rating (RMR) is a geomechanical classification system for rocks, developed by Z. T. Bieniawski between 1972 and 1973. [1] Since then it has undergone multiple modifications …

Most of the multi-parameter classification schemes (Wickham et al (1972) Bieniawski (1973, 1989) and Barton et al (1974)) were developed from civil engineering case histories in which …

This engineering classification system, which was developed by Bieniawski in 1973, utilises the following six rock mass parameters: 1. Uniaxial compressive strength of intact rock material. 2. …

Hoek-Brown强度准则现已广泛应用于矿业工程行业，其意义在于给岩土工程师提供了定量分析岩体应力状态和Bieniawski的岩体质量指标（RMR）及地质强度指标理论（GSI）理论之间的关 …

Bieniawski (1989) published a set of guidelines for the selection of support in tunnels in rock for which the value of RMR has been determined. These guidelines are reproduced in Table 4.5. …

1993年1月1日 · The RMR system (also called the Geomechanics Classification), proposed by Bieniawski in 1973 [9], and the Q system proposed by Barton et ale [7] in 1974, also include …

2008年1月1日 · In 1973 Bieniawski was the first who developed the rock mass ratin g (RMR) system (CSIR known as the South African Council of Scientific and Industrial Resarch), and …

Bieniawski (1976) published the details of a rock mass classification called the Geomechanics Classification or the Rock Mass Rating (RMR) system. Over the years, this system has been …

2018年2月1日 · From the RMR value, the rock load and rock support can be estimated from a support table presented in Bieniawski (1973). The rock load equation in Bieniawski's system is …

RMR是岩体力学中的岩石分类方法，即岩体地质力学分类。 该方案由宾尼亚夫斯基（Bieniawski）于1973年提出，包含：岩块强度、RQD值、节理间距、节理条件、地下水这5 …
