摘要
根据渤海湾盐渍软土地质特点,提出了滨海地区采用袋装砂井、土工格栅、砂垫层和超填预压联合排水固结路基基底的方法,实践证明该种软基的加固效果良好。介绍软土加固原理、施工工艺、路堤填筑技术措施、施工观测及注意事项。
In accordance with the salty soft soil geological conditions of Bohai Bay, the paper puts forward the construction procedure and technological control method for consolidating the road-bed foundation base by means of the sacked sand, geogrid, sand bedding course and extrafill pre-pressing combined-drainage. The facts show good effect of soft foundation consolidation.
