| 摘 要： | 提出了修正的RMR法——GSMR(General slope mass rating),较全面地考虑了离散权值(完整岩石强度,岩石质量指标,结构面间距)连续性权值修正、节理与边坡的相互关系、开挖方法、结构面与作用力夹角、人工边坡形态、地震应力、边坡高度、Romana的修正系数F3的修正。由于GSMR分级基本考虑了影响岩体力学性质的各种因素,因此用GSMR法选取岩体力学参数是一种工程上可行的方法。结合具体工程实例,证明了连续权值修正可代替离散权值来计算GSMR值,采用GSMR法确定了边坡稳定分析所需的岩体力学参数。

| Abstract: | General slope mass rating(GSMR) method is proposed. The continuous modification of discrete value which is composed of intact rock strength and rock quality designation and joint spacing, the modification of the relation between joint and slope, the excavation method, the inclination between joint plane and applied force, the state of artificial slope, the seism stress, the slope height and the revised coefficient F3 of Romana are considered. Because of this considering, rock mass mechanical parameters are determined by using the GSMR method, which is a workable method in engineering. That the discrete value can be replaced by the continuous modification to calculate the GSMR value is proved; and the rock mass mechanical parameters which are needed by the analysis for the slope stability are determined by using the GSMR method. |
