长江三峡工程库区交通工程地质环境研究

RESEARCH ON COMMUNICATION ENGINEERING GEOLOGY ENVIRONMENT IN THE THREE GORGES RESERVOIR AREA

三峡工程库区大多属中低山区 ,沟谷切割深、密度大 ,随着库区开发 ,不仅需补修淹没的公路 ,还将大量修筑新路 .兴建公路、铁路势必大量开挖边坡、掘进隧道 ,从而产生边坡失稳、隧道塌顶和疏干地下水等环境地质问题 .因此 ,防治地质灾害发生 ,对保护库区地质环境具有重要的现实意义 .通过对三峡库区交通工程现状及今后发展引起的各种地质环境问题的实例分析 ,提出了环境地质预测及防治对策 ,为三峡库区可持续发展 ,提供了有价值的地质资料 .

Three Gorges Reservoir Area belongs to middle and low-relief terrain, where gulch cutting is deep and dense. The road and railway construction will create large amount of excavation slope and tunnel piercing, which will introduce several environment geology problems, including the slope failure, tunnel collapse and groundwater drainage. With the reservoir development, not only does the inundated road need repair, but also the construction of a new road. So, preventing the geological hazard is of great significance for the protection in the reservoir area. Based on the analysis of the various examples of geological environment problems, the environment geology prediction and prevention techniques were advanced, which provided valuable geological data for the sustainable development in the Three Gorges Reservoir Area.
