Review on Expansion and Shrinkage Mechanism and New Treatment Methods of Expansive Soil |
| |
| Abstract: | Expansive soil has great harm and wide distribution, causes serious engineering problems, making the study of engineering treatment of expansive soil particularly important. Based on the analysis of physical and mechanical properties, expansion and shrinkage mechanism and influencing factors of expansive soil, three new methods for improving expansive soil were introduced. The results show that compared with the traditional improved technology, the new method has better improvement effect, lower cost and more environmental protection. |
