摘要
以襄樊—十堰高速公路韩家垭滑坡为背景,对其地质成因、物质组成、滑面物理力学特性、结构特征与运动特性进行了解,在此基础上对其变形机制进行深入分析,针对其变形规律建立相应的流变力学模型来反映其规律,并采用室内模型试验对滑坡的变形破坏全过程进行研究,利用试验所记录各部位测点的位移数据、现场监测数据和流变模型的位移变化曲线进行比较验证可知,位移曲线比较吻合,流变模型能较好地反映蠕动型滑坡的变形规律。
In allusion to a certain landslide of Xiangfan--Shiyan Expressway, some works have been done to find out its geological genesis, material composition, mechanical properties, structure features and motion characteristics based on which the deformation mechanism is analyzed. In addition, large-size geomechanics modelling test is adopted in order to study the process of development, evolvement, form in long geological history period in laboratory, and the curve of the displacement of the rheological model is compared with the data of laboratory physical model test and the monitoring. It is concluded that the creep-sliding characteristics are well reflected by the rheological mode.
