| 摘 要： | 讨论了软土地区的褐黄色硬壳层、暗绿色硬土层和所谓“次生硬土”等特殊土层的成因,提出后生作用对软土改造的观点。这类土往往是建构筑物的天然地基或桩基持力层,因此进一步搞清其成因变化将是研究土力学和工程特性的重要地质学基础。 |
| 关 键 词： | 软土 后生作用 褐黄色硬壳层和暗绿色硬土层 淋溶和潜育 |

| Abstract: | The epigenetic reformation of soft soil is talked over and some of epigenetic soils, the so -called brownish -yellow duricrust and grey -green bind in Shanghai district are attributed to the environmental change of oxideze - reduction. It is important for geotechnical engineering to study the genesis of the epigenetic soils in soft soil district, because of their improved mechanical properties. |
| Keywords: | soft soil epigenetic reformation brownish-yellow and grey-green bind leaching and gleying |
