Although joint spacing is an important index in rock mass structure classification , it ca n ' t be obtained in some regions such as riverbed , so the practicability of using those indexes which characterizing the integrity degree of rock mass to class the rock mass structure is studied , and good coincidence is shown in rock mass structure classification by joint spacing , integrity coefficient and number of joints in dam abutment
本文研究了用表征岩体完整程度的指标?完整性系数、 rqd及5m洞段节理条数j _ d (与体积节理数类似)划分岩体结构类型的可行性。对两岸坝肩部位，节理间距、完整性系数、 5m洞段节理条数这三项指标划分的岩体结构类型基本一致；河床坝基部位主要用rqd指标来判断岩体结构类型。
In order to scientifically manage exploration data , three - dimensional database composed of rock mass quality indices is established under the geodetic reference frame . those indices are obtained from adits , drill holes and outcrops . to efficiently make use of exploration data , finite testing results are spread to the extent which they can control in term of the characters of gradual change of rock mass quality
利用实测资料，研究了单指标(节理间距、完整性系数、 5m洞段节理条数)划分岩体质量等级的对应性，验证了单指标(完整性系数k _ v 、节理间距d )和双指标( k _ v d 1000 )划分岩体质量等级的一致性。
