摘要
根据真空 堆载联合预压加固高速公路软基的特点，介绍了某试验段路堤的施工工序，以及各阶段现场观测土体变形的特点．通过观测结果，对采用真空 堆载联合预压加固软基的效果进行分析，并提出理想的加荷计划．
An introduction is given to the working procedure of a certain section of a highway and the varions stages of field observation of the soil body on the basis of strengthening of soft foundation by vacuum surcharge prcloading.Through observation the effects of strengthening of the soft foundation by vacuum surcharge preloading are analysed and ideal loading plan is put forward.
