通过对江宁下蜀土的粒度组分、石英砂的表面结构以及其他地质现象的综合研究，探讨了下蜀土的成因及工程地质性质，表明下蜀土应为风成黄土，沉积时代为晚更新时期。下蜀土的粒度以粉砂含量最多，矿物成分以石英、长石、伊利石为主。下蜀土地层发育有黄色粉质粘土和黄褐色粘土两种土层，部分下蜀黄土具有中等湿陷性，有可能危害建筑物的安全。地下水与河水属淡水，水质较好，对钢筋混凝土无侵蚀性。

Through the comprehensive research on the grain size component of Xiashu loess in Jiangning, surface structure of quartz sand and other geological phenomenas, this paper explored the formation cause and engineering geological properties of Xiashu loess, showed the Xiashu loess should be eolian loess, deposition time was late update period. The grain size of Xiashu loess had many power sands, mineral constituents mainly of quartz, feldspar, illite. Xiashu soil foundation layer development had pink soil and yellow brown clay two layers, part of Xiashu loess had medium collapsibility, may be harmful to the safety of buildings. Groundwater and river water were fresh water, water quality was good, without corrosion to reinforced concrete.
