国标《工程岩体分级标准》应用中的几个问题

Discussion aboutseveral problems of the use of standard for engineering classification of rock masses

根据数个工程的实践经验,对国标应用中的几个问题:①国标在认识岩体力学性质中的作用;②工程岩体单元的划分;③结构面的统计和Kv值的选取;④岩体变形参数的估算等进行了讨论,可以作为工程岩体分级实践和国标修订时的参考。

According to experience in projects, the function of national code to study the mechanical properties of rockmass, deterrmination of element division of engineering rockmass, statistics of structural plane, deterrmination of Kv value, and evaluation of rockmass deformation parameters are discussed.
