利用流变介质模型，分析软岩立并并壁与粘弹塑性围岩的相互作用。根据现场实测结果及围岩压力与时间的关系，得到围岩应力、位移随时间的变化规律和粘塑性区的扩展规律。
Using the rheological model, the interaction between soft rock and parallel wall and viscoelastic plastic surrounding rock is analyzed. According to the field test results and the relationship between the surrounding rock pressure and time, the law of the stress and displacement of the surrounding rock with time and the expanding law of the viscoplastic region are obtained.
