摘要
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。
The rheologic model has been used to analyze the interaction between shaft wall and viscoelasticviscoplastic surrounding rock in soft rock stratum. Based on field testing results and dependency of surrounding rock pressure on time, we have obtained regularity on the variation of surrounding rock stress and displacement with time and the development of viscoplastic region.
