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
本文研究了用表徵巖體完整程度的指標?完整性系數、 rqd及5m洞段節理條數j _ d (與體積節理數類似)劃分巖體結構類型的可行性。對兩岸壩肩部位,節理間距、完整性系數、 5m洞段節理條數這三項指標劃分的巖體結構類型基本一致;河床壩基部位主要用rqd指標來判斷巖體結構類型。
