基于质量分级的岩体变形模量统计
|
摘要
收集筛选920个现场岩体变形模量试验值样本,按质量级别分别统计,据此给出各级别岩体变形模量试验值范围,将统计结果与《工程岩体分级标准》(GB50218-94)取值对比,为标准修订提出建议。收集114个岩体变形模量地质建议值样本,也按级别分别统计,据此给出各级别岩体变形模量地质建议值范围,将地质建议值统计结果与《水利水电工程地质勘察规范》(GB50487-2008)取值对比。统计及对比结果表明:《工程岩体分级标准》(GB50218-94)中,II,III级岩体变形模量分界线量值偏高;针对IV,V级岩体变形模量分界线,《工程岩体分级标准》(GB50218-94)给出的试验值界线与《水利水电工程地质勘察规范》(GB50487-2008)给出的地质建议值界线不协调;下阶段修编过程中需对以上问题加以关注。为增加《工程岩体分级标准》(GB50218-94)实用性,建议将各级别岩体变形模量地质建议值取值范围也纳入其中。
The parameters of each rock mass class provided in Standard for engineering classification of rock masses(GB50218-94) have little relation with rock masses classification and need to be verified.920 samples of in-situ deformation testing values were collected and statistically analyzed class by class;then the scope of deformation modulus of each class was given;and the statistical values were compared with the values in GB50218-94.Except for in-situ testing values,geological suggestion values of rock masses deformation moduli were also collected and analyzed class by class;and the statistical results were compared with the suggestion values in Code for engineering geological investigation of water resources and hydropower(GB50487-2008).Researching results indicate that the boundary between class II and III in GB50218-94 needs to be reduced;and the boundary between class IV and V in GB50218-94 is inconsistent with the value in GB50487-2008.It's suggested that the geological suggestion values also should be included in GB50218-94 to improve its practicability.
