Representative Achievements

1.Based on the National Natural Science Foundation of China , the study according to the geological environment of swamp turfy soil in seasonal frozen region, combine with the characteristic of engineering construction. Base on the winter freeze-thaw turfy soil field experiment outside, that getting the physical mechanical properties index, thermodynamic parameter and chemical property. Though the laboratory of turfy soil frost heave by different degree of decomposition, organic matter content, moisture content, temperature, the frost heave characteristics under different influencing factors can be get. Experiments of frost heave under different conditions are tested in laboratory to get index of each sample which can show the degree of frost heave, namely, the ratio of frost heave. Microstructure parameters of each sample are selected and quantitative analysed by WD-5 SEM before tests. From the perspective of macro and micro, frost heave mechanism of turfy soil in the season frozen can be summed up. Combined with the macroscopic and microscopic parameters, establish frost heave prediction model of turfy soil in season frozen zone.It may be provided the reasonable grounds and design consideration for line engineering construction of turfy soil in season frozen zone.

2.Based on Science and Technology Planning Project of Jilin Province China and National Science Foundation for Post-doctoral Scientists of China, the decomposition degree, organic matter content and microstructure characteristics of turfy soil in season-frozen area were analyzed. The failure modes of subgrade under freezing and non-freezing conditions with different treatment measures were studied. Based on this research, our group has got a set of feasible calculation methods and gives a group of models. Combined with the model and monitoring data, the characteristics of settlement deformation, stress and strain of turfy subgrade in seasonal-freezing area with different treatment measures were simulated and analyzed. The effects of different engineering treatment methods on the wetland environment of turfy soil were studied from two aspects of engineering feasibility and ecological impact, and the foundation treatment suggestions of turfy soil area in seasonally-frozen area were put forward.
