地下水的作用,是影响岩石洞室围岩稳定的重要因素之一。在开挖洞室时会遇到地下水,结果在它的作用下导致围岩失稳,甚至造成灾害性事故,使工程蒙受严重经济损失。这一情况说明,研究地下水对洞室围岩稳定的影响,确是一个具有重要现实意义的课题。(一)岩体中地下水的特征岩体中地下水存于岩体的裂隙、溶隙或孔
The role of groundwater is one of the important factors that affect the stability of surrounding rock in rock caverns. Groundwater will be encountered during the excavation of the caverns. As a result, the surrounding rock will become unstable due to its action and may even cause a catastrophic accident and cause serious economic losses to the project. This situation shows that studying the impact of groundwater on the stability of the surrounding rock in the cavern is indeed a topic of great practical significance.
