摘　　要：通过中江高速公路改扩建工程在建设过程中路-桥方案的比选,分析深层软基处理方案在中江高速公路改扩建中的适用性及深层软基处理均方工程造价,总结不同路段、不同填土高度条件下路-桥方案的比选,比选分析路段长度与软基处理方案每m^(2)工程造价的相关性曲线。结合现场施工条件,择优选取软基处理与桥梁方案,并通过工程实践进行验证。Being based on Zhong-jiang Expressway Reconstruction and Expansion Project,the applicability and economic viability of deep soil treatment schemes of embankment and bridge plans have been discussed.The selection criteria for embankment and bridge plans under different road sections and fill heightshas been summed up,and the correlation curve between the length of the selected road section and the cost per square meter of the soft foundation treatment schemehas been compared.Considering on-situ construction conditions,the optimal selection of soft foundation treatment and bridge plans has been made and validated through examples.

关 键 词：路桥方案 工程造价比选 实践验证
