Abstract:
tunnel belongs to underground engineering, which is a typical geological engineering. The geological conditions are uncertain, especially the collapse accident of loess surrounding rock tunnel is common. The construction of loess tunnel is very difficult, the surrounding rock has almost no self-stability ability, and it is easy to cause collapse in the construction In this paper, the process of loess tunnel collapse and its objective influencing factors are briefly discussed, which can be used as a reference for the prevention of loess tunnel collapse.
隧道属于地下工程,是典型的地质工程,地质条件存在不确定性,尤其是黄土围岩隧道塌方事故屡见不鲜。黄土隧道施工难度大,围岩几乎无自稳能力,施工中极易造成坍塌。就黄土隧道塌方的过程及其客观影响因素作了简要的论述,可为相关黄土隧道预防塌方作出参考。
