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。

Abstract：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.

Key words： rock mechanics rock masses classification deformation modulus testing value geological suggestion value statistical analysis
