摘　　要：为了解润扬长江大桥北锚基础岩石的流变力学特性,针对北锚基础区域的岩样,通过模拟其受力的实际情况,采用岩石双轴流变试验机进行了单轴压缩蠕变试验,并选用广义的Kelvin模型进行了参数拟合分析,掌握了岩石蠕变的基本规律,并获得了粘滞系数等相关的流变力学参数。For knowing about rock rheological characteristic of north anchor block in Runyang Yangtze River bridge foundation engineering, the uniaxial compression creep testing has been studied by simulating the actual lpading state of the rock using biaxial rock rheological testing equipment (CSS-1950 type). At the same time the generalized Kelvin mode has been selected for fitting analysis, we find out the creep basic law of the rock, and some correlative rheological parameters are also gained, such as viscosity factor, etc.
