Soil Mini-Scale Steucture Changing Analysis In City Groundwater Chemisty Environment

Groundwater is one of the the most activity and exquisite elements in city geological environment inscapes, and also the most important geological construction power. Long time water-soil interaction is not only influence the components of both the water and soil but also their properties. Some problems in nature and project can be answered by this research. The essence of the water- soil interaction is at inner relations among groundwater environment—structure(component) — strength. Formers do much research in this field, but only are localization at macroscopical phenomena or engineering instance analysis. There are few research on soil mini-scale structure change doing by systematic simulation experiments. At this point the paper study the soil structure development history, and find out mostly chemistry ingredient and constant elements, and learn the elements' being form and chemistry change in the soil, and analyse how the change influence the soil structure and strength. Thisstudy a I so use SEMn CT and ana I yt i ca I chem i st ry and other sc i ence methods to observe soi I structure components' character and quantity change, and soi I structure change. At last analysis by figures. This research has signify meaning on presenting soil mini-scale structure change under water- soi I interaction, and on relations between structure change and strength. The conclusion offer a theory bases for decreasing and defending geological disaster in city construct ion. It is the precondition for city safe and preventing disaster, and the base for city's continuous development.
