| 摘 要： | 文将隧道围岩和衬砌材料分别视为粘弹性流体和弹性体，、研究了圆形隧道的围岩压力随时间的变化规律，弃给出了理论公式。为了对理论结果进行验证，选择了流变性较显著的相似材料做了模拟实验。本文的成果对于软岩隧道衬砌的设计，以及寻求运营隧道衬砌开裂的对策，提供了又一理论模拟。

| Abstract: | Considering the liner and surrounding rock mass as elastic body and viscoelastjc fluid respectively, this paper studies the rheolo- gical pressure of surrounding rock mass on circular tunnel ner. A formula is proposed to compute the pressure. Creep model tests are carried out to verify the theoretical results. The achie- vements of this results of this research could be used as a theoretical basis in the design and management of tunnels in soft grounds. |
