降雨诱发滑坡的水文地质因素分析

Analysis of Hydrogeological Factors in Slope Induced by Rainfall

地下水对工程活动和地质环境的作用与影响日益显著,几乎所有的重大工程地质问题都与地下水相关联。但目前岩土工程界对地下水的认识和研究仍显不足,研究地下水的形成、赋存特点、类型、含水层、隔水层等以及相关的含水介质的渗透性能、地下水的动态特征和运动规律、水文地质模型的建立和水文地质模拟,地下水与岩土的关系和相互作用对地下水诱发的工程事故和地质灾害研究有着重要影响。本文主要就降雨和地下水诱发的边坡失稳问题进行了系统分析和论述。

The action and effect of groundwater on engineering projects and their environments are increasingly apparent and more deeply known in the practice. All most every impotent project has the action of groundwater. However, the ground water function is not full realized in the present project reconnaissance and the design. The study of the ground water the formation, the type and characteristic of groundwater, the water-bearing stratum, the aquiclude, the ground water dynamic characteristic and the law of motion the hydrology geology simulation is very is impotent. It is created the insufficiency problem concerning with hydrogeology and engineering geology. In this article, it is analyzed the influence of ground water in engineering geology and taken the landslide for example.
