摘要
坝基岩体质量分级关系到大坝工程的安全性和经济性。通过对坝基岩体质量分级要素及各要素之间的联系进行研究,得出岩体分级各要素界限指标的对应值。在此基础上提出适用于本工程坝基岩体质量分级的单因素和双因素标准。并应用此标准对该坝基进行岩体质量分级。
Rock quality rating is related to the safety and economy of dam projects. The limit index value of each rating ele ment is obtained by studying rating elements and their relationship. Based on this, the standards of single factor and double fac tors are given and applied for the rock quality rating of this dam＇s foundation.
