Research on Treatment Measures for Soft Soil Roadbed of Municipal Roads
The scientificity treatment of road soft soil subgrade is crucial for ensuring road stability and extending road service life.The article introduces the composite roadbed reinforcement measures of PTC piles,sand piles,and CFG piles.Load tests were conducted on test piles using different reinforcement measures,and the settlement of the roadbed and changes in soil pore water pressure at different depths were monitored 14 weeks after completion.The results show that all test piles meet the design requirements,and the average displacement of sand piles is the highest;the settlement of the roadbed is the highest when using sand pile composite reinforcement measures,and the improvement effect of this reinforcement measure on roadbed settlement is poor.Relatively,the average displacement of a single pile and the settlement of the roadbed are minimized after using PTC pile reinforcement.
