By the Transportation Research Institute of Jiangsu Province, Nanjing Institute of Geosynthetics, Southeast University Department of Civil Engineering, Ministry of Communications Road Research Institute participated in “soft soil, over wet road high-grade road construction technology research” in February 28, 1990 Day passed the provincial appraisal. Based on the research on the characteristics and physical and mechanical properties of the soft ground of Xinxu-1 highway in Lianyungang and the investigation of the old road, the paper puts forward that using self-contained preloading and sand pad Method of treating soft ground. Lianyungang Xinxu highway soil and soft soil thickness is very typical in our country, after a large number of experimental data
