基于RMR法和BQ法的边坡工程岩体质量评级及力学参数确定
Quality Classification and Mechanical Parameters Confirmation of Slope Engineering Rock Mass based on RMR and BQ Methods
【摘要】 根据现场勘探资料和室内试验数据,并综合考虑边坡工程施工特性等因素,采用RMR法和BQ法分别对矿区边坡的工程岩体进行了质量分级和评判,综合确定了矿区各岩体的强度范围。实例分析表明综合预测方法能够更加科学地预测岩质边坡质量的等级问题,从而为采取经济、合理的支护加固措施,提供更可靠的依据。
【Abstract】 Based on field exploration data and laboratory test data,comprehensively considered construction property and other factors of slope engineering,quality classification and evaluation were done on engineering rock mass of mine slope by adopted RMR and BQ methods,strength range of each rock mass of mining area were confirmed comprehensively.The example analysis indicates comprehensive forecasting method could predict hierarchical problem of rock slope quality more scientific,and it also can provide more reliable basis for adopt economical and reasonable support treatments.
