摘要
阐述了岩体质量及其影响因素的复杂性和不确定性 ,采用模糊数学方法建立了考虑岩石单轴抗压强度、RQD、裂隙间距、裂隙面粗糙度系数、裂隙水压力与最大应力比值的 5因素洞室围岩综合评判模型 ,以及考虑岩体纵波波速、完整性系数、变形模量、均一性系数、RQD、裂隙间距、承压水顶板岩体自重应力与承压水头比值的 7因素大坝建基面模糊优选模型 .
Based on the description of the complexity and indeterminacy of rock quality and some affecting factors, a model for comprehensive evaluation of cavern adjoining rock, in which 5 factors are considered, namely uniaxial compressive strength of rock, RQD, interval between fissures, roughness coefficient of fissure surfaces, and the ratio of fissure water pressure to the maximum stress, is established by use of the fuzzy mathematical method. Besides, a fuzzy optimal model for dam foundation building surface is also developed, in which 7 factors are considered, i.e. propagation velocity of primary waves, integrity coefficient, deformation modulus, uniformity coefficient, RQD, interval between fissures, and the ratio of the self-weight of rock mass to the artesian head.
