  • The application and effect of soft ground treatment in Shanghai-Jiangsu-Zhejiang highway (Jiangsu section) are investigated. Through the researches, it can be concluded that the surcharge preloading, wet grouting piles and prestressed pipe piles are the main treatment methods. The soft ground treatment generally achieves the anticipated goal with no phenomenon of vehicle dumping. Ruts and cracks occur mostly in the section of soft soil, large settlement and the junction of different soft ground treatments. The micro surfacing and thermal regeneration are adopted to repair the ruts while the grouting is adopted to repair the transverse cracks, respectively. The ruts and transverse cracks can be effectively controlled.
