| 摘 要： | 本文首先介绍用弹塑性理论研究无支护隧洞洞壁围岩的稳定性。当判别为不稳定时,隧洞需立即支护。然后,用粘弹性理论研究支护和围岩联合作用时的稳定性。并介绍用径向位移与位移速度的流变数学模式研究围岩的稳定性。

| Abstract: | The paper presents a method checking and forecasting the stability of underground works according to the deformation on the wall of opening.First of all, the stability of adjoining rocks on the wall of a tunnel without any support is studied, in the case that adjoining rocks are determined to be instable, the tunnel is needs prompt support. The stability under the combined actions of adjoining rocks and supports is studied by the visco-elastic theory. The rheological mathematical model of radial displacement and its velocity are presented to study the stability of adjoining rocks. |
