摘　　要：结合温州围垦区市政道路项目,对真空堆载联合预压的设计要点、施工工艺及加固效果等进行了分析总结。围垦吹填区深厚软土路基经真空堆载联合预压处理后,各土层物理力学性质得到明显改善,此方法可有效减少道路工后沉降,提高路基承载力。In combination with the projects of municipal roads in Wenzhou reclamation area,the design points,construction technology and reinforcement effect of the vacuum-mound preloading method are analyzed and summarized.The physical and mechanical properties of each soil layer in the deep soft soil subgrade of the reclamation and hydraulic fill area have been significantly improved after the vacuum-mound preloading method.This method can effectively reduce the post construction settlement of the road and improve the bearing capacity of the subgrade.
