| 摘 要： | 文章针对环境污染日益严重,雨水对边坡稳定性影响也越来越严重的问题,提出边坡中水土作用理论,其定义为发生在边坡中水溶液与环境、固体表面、矿物颗粒、气体、生物以及深层地下水或土之间的各种物理化学作用,其中水溶液是一种主要媒介。简要分析边坡在降雨入渗过程中水土化学作用条件与作用类型,详细研究溶解与沉淀作用、交换与吸附作用、氧化还原作用、以及水解与络合作用等,分析水土化学作用对土的强度与变形特性起到强化或弱化作用。综合阐述土体性质、地质环境、雨水性质、人类社会活动等因素对水土化学作用可能造成的影响。

| Abstract: | Aiming at the problem on slope stability influence is more and more serious because the environment pollution is continuously serious,the theory of water-soil chemical interaction is mentioned in this paper.The water-soil chemical interaction is defined for the various physics chemical action between the water aqua that is a kind of main medium with environment,solid surface,mineral grain,air,living creatures and deep groundwater or soil in the slope.We analyze with synopsis the interaction conditions and types in the process of rain infiltrating.We study in detail the action of fuse and sedimentation,the action of exchange and adsorption,the action of oxidize and restore,and the action of water solution and water combination etc.At the same time,we analyze the strength of soil and the characteristic of transform enhanced or weakened by the water-soil chemical interaction.Lastly,we elaborate synthetically some factors including soil property,geology environment,rain property,mankind's social activity etc.,which may affect the water-soil chemical interaction. |
