摘　　要：侵蚀性环境水的形成及其侵蚀能力不仅与岩石组分密切相关，而且与地下水在岩层中的运动特征有关。地下水的渗透速度影响着其与岩石的反应速度，而地质构造、岩层厚度、岩石破碎程度及地下水的补给状况等则是影响地下水运动的重要因素。本文就地下水在岩层中的运动过程、反应过程及影响因素进行了分析研究，通过对乐所２号隧道混凝土腐蚀状况的分析，弄清了工程建筑物周围地质状况及地下水运动规律，对混凝土腐蚀机理研究、腐蚀程度评价有着重要的意义。The formation of corrosive environment water has not only close relationship with rock composition but relates directly also to movement characteristics of groundwater. Infiltration velocity of groundwater influences its reaction rates with rocks. Geological structure, strata depth, rupture degree and supply of groundwater are major influence factors. This paper analyses the movement of groundwater and its reaction process with rocks. Through studies on concrete corrosion in Lesuo No.2 tunnel, the authors conclude that a good understanding geological conditions and movement of groundwater is helpful to studies on corrosion mechanism and evaluation of corrosion degree.
