| Soft foundation treatment is a technical problem in the road construction, Soft foundation treatment effect not only have some connection with the design and calculation methods,but also is closely related to the control of the construction quality. As the theoretical calculation of soft soil treatment, the design incomplete and the Soft construction quality is difficult to control,so often do not get a good treatment effect.To Jin-hong hightway features include transport volume for incoming big and complex geological conditions, drainage difficult, time is short, fast and so filling rate , Jin-hong hightway embankment construction process, the actual situation of engineering, conducted a number of changes to the design, optimization, eventually made a variety of different geological conditions comprehensive approach. This article is from the road entering the port is different from the characteristics of the road , Soft combination of on-site comprehensive treatment measures , Numerical simulation and field monitoring data of the road entering the port during the construction of deformation mechanism and the treatment effect ,And reached the lake embankment construction in soft ground stability safety control targets. The main conclusions are:1) Numerical simulation reproduce well on-site construction problems and the effect of control , explains the finite element method to evaluate the role of soft soil under load stability is possible ;On the other hand shows the comprehensive control by the optimized method is effective and feasible .2) Optimization of Soft-site monitoring data before and after the program that: Comprehensive management approach optimized to effectively control the settlement, pore pressure, lateral displacement of a substantial change , Again verified by the optimized comprehensive approach is effective, but also verifies the use of finite element numerical simulation is correct and applicable.3) Construction monitoring data used to control the stability of security indicators :During loading, filling the maximum subsidence rate loading control 10mm/day the following ;Comprehensive pore pressure coefficient B <0.5; maximum lateral displacement control within the 0.6mm/day before proceeding to the lower load.4) To Jin-hong hightway the embankment on soft clay for the construction of the deformation of subsidence problems arise, Carried out geological survey and the stability of the evaluation meeting,Dongting Lake region raised embankment construction on soft foundation and the key technical parameters and used to guide construction. To optimize the soft embankment design integrated approach to improve rational ,Using surveillance data to control the construction of stability as indicators of enhanced security Soft Construction Quality Control , to ensure the safety of Construction period. Which may use for reference to design and construct the subgrade on similar soft ground.
