地下工程开挖遭遇突泥涌水灾害的先兆表现

Foregleam of Mud Gushing Disaster in Underground Engineering Excavation

由于受勘测手段的限制,目前大多数地下工程开挖建设过程都有一定的风险性,因为对前方地质情况不能全面清晰的了解,在发生突发的地下地质灾害时往往会造成较大的损失,特别是地下工程在建设过程中发生突泥涌水灾害时,几乎是在瞬间淹没整个工作空间,造成一定程度的人员伤亡和经济损失。如何预防灾害的发生,或是如何顺利避险,是值得地下工程建设者们共同持续深入研究的。结合自身工作经历介绍几种突泥涌水灾害发生的先兆表现,并提出预防建议。

At present,most underground engineering excavation and construction process has certain risks due to the limitation of survey means.Because the geological conditions in front of us can not be fully and clearly understood,great losses will often be caused when unexpected underground geological disasters occur.Especially when mud gushing disaster occurs in the construction process of underground engineering,the whole working space is almost instantaneously submerged,resulting in a certain degree of casualties and economic losses.How to prevent disasters or how to avoid them smoothly is worth continuous and in-depth study by underground engineers.In this paper,several foregleams of mud gushing disasters are introduced based on our own work experience and preventive suggestions are put forward.
