摘要
岩体力学参数的选取具有较大的繁冗性或主观性,在工程实践中具有较大的弊端。结合HoekBrown经验强度准则及区间数学理论对岩体力学参数区间量化,该法以区间值表示边坡的稳定性状况,可体现稳定性的不确定性。以湖南319国道泸溪段滑坡为例,采用极限平衡法与有限差分法进行数值分析,表明该边坡处于不稳定状态,为加固设计提供了理论依据。
The redundancy or subjectivity of selection rock mechanical parameter is a great disadvantage in the practice of engineering. With Hoek-Brown strength criterion interval and interval mathematics theory to rock mechanical parameters quantify interval represents the method to slope stability conditions reflecting the stability of uncertainty. In paragraph 319 national highway in Hunan province Luxi landslide for example,with limit equilibrium method and finite difference method for numerical analysis,indicated that the slope was in an unstable state,and which provided theoretical basis for design.
