基于岩石风化的深度效应和时间效应,根据岩体风化特点和考虑深度效应的岩体风化Boltzmann曲线模型的基础上,引入表层岩石风化的时间效应,提出考虑时间、深度效应的岩体风化模型,并对影响岩体强度分布的因素展开了分析,研究表明:最大影响深度h_m与形状函数系数b、表层岩体强度S_0和强度分布影响区域中心点对应的深度H_0成正比例关系,与岩石风化影响下限强度值S_H成反比例关系。最后统计分析了不同因素在不同位置对岩体强度参数的影响程度,确定了浅层岩石风化的时间效应为影响岩石强度分布的主要因素,进而说明以此引入时间因子是可行的,为进一步认识岩体强度在时间和空间上的分布情况提供了一定依据。
Based on the weathering effect and time effect of rock weathering, based on the weathering characteristics of rock mass and the weathering Boltzmann curve model of rock mass considering depth effect, the time effect of surface rock weathering is introduced and the weathering model of rock mass considering time and depth effect is proposed. The analysis shows that the maximum impact depth h_m is directly proportional to the shape function coefficient b, the strength of surface rock mass S_0 and the depth H_0 corresponding to the center point of the intensity distribution, which is in direct proportion to the influence of rock weathering The lower intensity value S_H is inversely proportional. Finally, the influence of different factors on rock mass strength parameters in different positions is statistically analyzed. It is determined that the time effect of shallow rock weathering is the main factor influencing the rock strength distribution. Therefore, it is feasible to introduce the time factor. In order to further understand The strength of rock mass in time and space distribution provides a certain basis.
