摘　　要：青藏线、川藏线等国防公路边坡大多为岩石结构,由于边坡岩石建造环境的复杂性、岩体风化程度的差异性、微裂隙发育不均匀性等地质因素,及取样不规范或现场试验位置、野外岩性定名、试样加工测试等人为因素,测试数据具有离散性,致使岩体变形和强度等参数存在误差,给边坡治理带来困难。以岩体赋存地质环境信息、岩体基本质量定性判断信息、完整岩块试验室测试数据及人为因素为条件属性,以岩体抗剪强度指标建议值为决策属性,建立基于粗集理论的岩体强度参数确定模型,为国防公路边坡治理提供较科学的参考数据。It is the common structure of the slope in the Qinghai-Tibet road and the Sichuan-Tibet road,etc.The testing data have discreteness characteristics owing to geologic factors for complexities of rock formation,diversities of rock weathering, nonuniform-distributed micro-fissures,and artificial influence factors for nonstandard sampling methods,unfit places of in-situ testing,field lithology judgement,grinding and testing of samples,etc.It is difficult for slope governance according to the error data of the rock mass deformation and strength.Based on rough sets theory,The rock mass strength parameters-selected model can built on condition attribute including geologic environment of rock occurrence,qualitative judgment of rock mass basic quality,laboratory strength data of intact rock and artificial influence factors,and on shearing strength parameters of rock mass treated as decision attribute.It can provide scientific reference data for harnessing side slope in the national highway.
