摘 要: 在室內(nèi)對硅藻巖進(jìn)行了主要物理力學(xué)指標(biāo)測定和蠕變試驗(yàn)的基礎(chǔ)上分析了軟弱巖體的流變特性。根據(jù)Berger模型，建立了軟弱巖體的流變狀態(tài)方程和蠕變方程來分析支護(hù)前圍巖移動規(guī)律和支護(hù)后流變地壓的增長規(guī)律，同時(shí)還研究了軟弱巖體的長期強(qiáng)度。

Abstract: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.
Key words: flabby rock rheologic pressure creep long-term strength nonlinear regression analyses
