摘要
在室内对硅藻岩进行了主要物理力学指标测定和蠕变试验的基础上，分析了软弱岩体的流变特性。根据Ｂｅｒｇｅｒ模型，建立了软弱岩体的流变状态方程和蠕变方程来分析支护前围岩移动规律和支护后流变地压的增长规律。
The rheologic characteristics of flabby rock have been analyzed on the basis of siliceous rock's primary physicomechanical targets determined by indoor testing and creep tests. According to Berger model, rheologic constitutive equation and creep equation of flabby rock have been set in order to analyse moving regularity of surrounding rock before supporting and increasing regularity of rheologic pressure after supporting. The long term strength of flabby rock has been studied in the mean time.
