| Abstract: | Accoeding to the drill hole sample and spot testing of Jijie,we have got the swelling coefficient of Jijie expensive soil under different P and the swelling amount of it at different depth.And we have an analysis of the swelling and contraction engineering characteristics of Jijie expansive soil in combination with the mineralogical and chemical composition.We have carried out the statistics of water content of Jijie soil layer,then got the variation curve of water content of Jijie expansive soil and analysed in combination with the deformation amount,which will provide the foundation for the engineering construction in the expansive soil area. |
| Keywords: | Jijie Expansive Soil Expansibility Deformation Amount Water Content Variation Gejiu Yunnan |
