宁明膨涨土是我国最早发现的典型膨胀土之一,在地质成因、胀缩性能发育程度等方面均具有一定代表性。 本文是对广西宁明膨胀土宏观,微观研究的总结。 研究中承蒙广西建委综合设计院、86391部队、南京地质古生物研究所、南京土壤研究所及我系兄弟教研室同志们的多方指导与帮助,在此一并表示谢忱。 Ningming swell is one of the earliest expansive soils found in China. It has certain representativeness in the aspects of geologic origin, degree of expansion and contraction performance development, and so on. This article is a summary of macro and micro studies on expansive soils in Ningming, Guangxi. In the study, thanks to the multidimensioned guidance and help from Guangxi Construction Committee Comprehensive Design Institute, 86391 troops, Nanjing Institute of Geology and Palaeontology, Nanjing Institute of Soil Science and my brothers and sisters teaching department, I would like to express my gratitude.
