【摘要】 采用自行研制的重力杠杆式岩石蠕变试验机并配备三轴压力室，从而对泥岩进行了三轴蠕变试验．根据试验结果，提出了软弱岩体的蠕变理论，并用于地下工程应力场、位移场和流变地压的分析与计算．通过算例分析，井巷围岩周边位移和流变地压的发展规律符合现场实际情况更多还原

【Abstract】 Authors have made triaxial creep tests with mudstone on the gravity lever type rock creep testing machine developed by themselves and provided with triaxial pressure cell. According to the testing results,the creep theory about flabby rocks has been put forward to analyse the stress field,displacement field and rheologic crustal pressure of the underground engineering. By means of calculating examples,the developing regularity of displacement on the periphery of shaft or tunnel′s surrounding rock and rheologic pressure conform to on the spot reality.更多还原
