揭普高速公路榕江平原段软土路基处理探讨

Discussion on Soft Soil Roadbed Disposal of Rongjiang Plain Segment belonging to Jiepu Highway

广东揭普高速公路沿线为典型的沿海三角洲地区,软土广泛分布,且层厚、埋深不一,物理力学性质差异大。针对本段软土路基的特点,采用袋装砂井加砂垫层超载预压的方法对地基进行排水固结处理,取得了明显的工程效益和社会效益。

It is typical delta area along the sea beside Guangdong Jiepu Expressway with soft ground distributing widely and different thickness and depth,and physics mechanics in much difference. Aiming at the character of this soft soil roadbed,a method of sand well,sand cushion and overloading prepress was used in consolidation by drainage,which gets obvious engineering benefit and social benefit.
