一、机械潜蚀的一般概念潜蚀(管流现象)是和地下水活动有关的物理地质现象之一,近代分为机械潜蚀及化学潜蚀两种。化学潜蚀由岩石中可溶盐的淋滤及冲蚀而形成,而机械潜蚀则是因渗透水流将岩石松散并将小颗粒带走而发生。潜蚀(或管流现象)这个名词(суффозия)苏联著名地质学家А.П.巴甫洛夫在1898年就用了。按照他的意见,这是一种可溶化合物的淋滤以致土沉陷 I. The general concept of mechanical latent corrosion The latent corrosion (pipe flow phenomenon) is one of the physical geological phenomena related to groundwater activity. In modern times, it is classified into mechanical latent corrosion and chemical latent corrosion. Chemical latent corrosion is formed by the leaching and erosion of soluble salts in rocks, while mechanical subsidence occurs because the permeate flow loosens the rock and removes small particles. The term lag (or flow phenomenon) was used by the famous Soviet geologist А. П. Pavlov in 1898. According to his opinion, this is a leaching of soluble compounds that causes soil subsidence.
