Abstract:as a kind of soft soil treatment technology with the advantages of environmental protection and economy, in-situ shallow solidification technology can be applied to reinforce the road subgrade, but there are few experimental results in this field. Using the same technology, materials and mix proportion, the stability and reliability of the technology were studied in the river crossing and supporting road project of Kunyang road and the new construction project of S3 highway. The a large number of results show that the bearing capacity of the two projects after shallow solidification treatment can meet the design requirements, and the maximum settlement, the maximum settlement and the total settlement of the two projects can meet the design requirements The absolute value and distribution range of the maximum rebound amount and rebound rate are close.
