摘　　要：为促进滨海地区县域公路的建设,提高工程质量,调查连江通港大道工程概况,通过分析软基路段的地质勘察资料,研究采用真空堆载联合预压+塑料排水板法对软基路段的加固过程,同时对地面沉降、孔隙水压力、深层土体水平位移进行监测。结合理论分析,将收集到的实测数据进行处理。结果表明,软基加固效果显著,能够达到设计要求,可为类似工程建设提供参考。In order to promote the construction of coastal areas of county roads,improve project quality,a survey on the general situation of Lianjiang Tonggang Road was made. Through analyzing the geological exploration data of the soft foundation,studying the process of using vacuum and surcharge combined preloading plus plastic drain board method to reinforce the soft ground section,monitoring ground subsidence,pore water pressure,horizontal displacements of deep soil simultaneously. Theoretical analysis was combined when the measurement data collected was processed. The results shows that the effect of soft foundation reinforcement is significant,can meet the design requirements and can provide references for similar projects.
