| Soft Ground subsidence and ground treatment methods of soil mechanics in the study is an important issue on soil mechanics,based on the Yanjiang highway in Anhui province settlement observation and tests at the scene,the paper on soft ground subsidence and treatment programmes carried out in-depth study,the main conclusions are as follows:1,the law of the surface subsidence,analysis of that theoretical calculations generally less than the actual measurement is due to soft ground along the river in Anhui has strong ability to lateral deformation caused by the deformation characteristics.2,Research on a different foundation treatment approach to the tiered settlement,lateral deformation,soil pressure and pore water pressure changes in the law,the results showed that:-tiered settlement "S" swing curve is determined by the soil foundation heterogeneity of soil;the plastic plates of the observation section of the horizontal displacement is not on the surface is up to the subgrade form and foundation soil nature;soil pressure and the trend of changes in basically the same high embankment construction,the measured soil pressure than the actual roadbed soil load small,and the soil RCC,consolidation,density and other factors related to the ultra-pore pressure generated by the permeability of soil and upper load of embankment construction,with different processing methods and laying the foundation depth varies.3,the impact of the settlement on the factors that:ground treatment methods,soft soil depth and embankment fill height of the main factors affecting the settlement,basically subgrade settlement with a high degree of roadbed fill increased with increasing to a certain extent but lag behind.4,the foundation works deal with different methods showed that:CFG pile in the smallest of the settlement,plastic plates of handling the largest settlement,in accordance with the actual situation on specific projects identified.
