岩体质量评价利用岩体质量指标评定岩体的工程地质性质的工作。它将工程地质评价和岩体工程地质特性参数，以及岩体工程设计定量地联系起来，使工程实践经验得以定量表述。因此，它是工程地质评价定量化的重要发展。国际上应用较广的有3类：岩石结构评价RSR系统、岩体地质力学评价RMS系统及岩体质量Q系统。在中国，有杨子文提出的岩体质量指标，谷德振、黄鼎成提出的岩体质量分级等多种方案。岩石结构评价RSR系统。岩体质量的表述式为RSR＝A＋B＋C式中 A代表一般地质状态、岩石类型、岩石坚硬程度及地质构造扰动程度的参数;B代表节理状态、密集程度和走向与洞轴关系的参数;C代表地下水涌水量及节理状态的参数。岩石地质力学评价 RMS系统。根据岩石强度、岩心获得率、节理间距、节理状态、地下水涌水量等分级，并考虑节理和隧洞的相对关系，进行分数校正。岩体质量Q系统。岩体质量Q值表述式为式中RQD为长于10厘米的岩心获得率；Jn为节理组数；Jr为节理面粗糙度;Ja为节理蚀变程度;Jw为裂隙水的影响；SRF为地应力的影响。杨子文认为岩体的工程性质，主要受岩体的完整程度、岩块的质量、风化程度和水的作用等 4方面因素的影响。岩体性质的变化，必然要表现为这 4个因素指标的变化。他提出的岩体质量表达式为 M=ISKYKR或 式中M为岩体质量指标；I为岩体完整性系数,，其中Vp为岩体弹性波纵波速度，V0为岩块弹性波纵波速度,S为岩石质量系数,,其中RD、 ED?直鹞庋铱榈牡ブ岣煽寡骨慷群透裳铱榈牡阅Ａ浚?RS为软弱岩块抗压强度的上限，取300千克/平方厘米,ES代表软弱岩块弹性模量的上限，取6.6×104千克/平方厘米；KY为岩石风化系数，，其中RC为新鲜岩块的干抗压强度；KR为岩石软化系数，，其中RW为欲测岩块的饱和抗压强度。根据I、S、KY、KR4个参数可以计算出岩体质量M 。M值愈大，岩体质量愈好。按照M值的大小，将岩体分为5类：M>3，好岩体；1～3，较好岩体；0.12～1.0,中等岩体；0.01～0.12，较坏岩体；<0.01，坏岩体。在以上各种岩体质量评价方法中，均考虑了岩体的完整性、节理状态和岩石特性等因素，相互之间有一定的可比性。目前，岩体质量评价方法还在研究和发展中，采用模糊数学或灰色评判是进一步研究的方向。
