摘　　要：探讨连云港地区软土的工程特性,通过对大量试验数据的分析,给出该地区软土数值计算的参考数据,对采用砂垫层预压和真空预压等排水固结加固连云港地区软基方法进行对比分析,给出适合于该地区软土地基沉降计算的实用简化模型和沉降计算方法。探讨连云港地区公路设计的极限填土高度,指出该地区公路低路堤设计的必要性。对今后该地区的公路软土地基处理具有一定的借鉴意义。The engineering properties of the soft ground in Lianyungang area are discussed.Through a lot of experiments,it presents the reference data of the soft ground in Lianyungang area which can be used in digital calculation.After comparing with the methods of consolidating the soft ground by vacuum preloading and sand cushion preloading,the paper provides the model and method to calculate the settlement of the soft ground in Lianyungang area.The ultimate filling depth for the subgrade design in this area is also discussed,which shows the necessity to adopt the method of low embankment for the subgrade design in this area.The method discussed in this paper is expected to be used in similar projects.
