Ultra-deep soft foundation revetment structure capable of laterally reducing load under large side load condition and construction method
The invention provides an ultra-deep soft foundation revetment structure capable of laterally reducing load under a large side load condition and a construction method. The core structure comprises a dike core structure, a drainage structure, a foundation pile body structure, a slope dike protection structure and a soil body structure. According to the construction method, the multiple horizontally-connected large thin-wall hollow steel structures are hit into soft soil, the soft soil in the steel structures is reinforced, materials with good horizontal deformation resistance are backfilled, and the special thin-wall steel and soil dike core structure with better integrity is formed to replace conventional sand quilt or riprap dike core materials. Lateral deformation of the ultra-deep soft foundation revetment structure under the condition of rear loading high additional stress can be reduced, the problems that the safety of the revetment structure in ultra-deep soft soil is poor, and the sea area occupied area is large are solved, and the defects existing in the prior art are well overcome.
本发明提供了大边载条件下可侧向减载的超深软基护岸结构及建造方法。本发明核心结构为堤心结构、排水结构、地基桩体结构、斜坡护堤结构和土体结构；本发明的建造方法，将多个水平连接的大型薄壁空心钢制结构打入软土，并对钢制结构内部软土进行加固以及回填抗水平变形性能较好的材料，形成整体性更佳的“薄壁钢+土”特殊堤心结构替代常规的砂被或抛石堤心材料。本发明能够减小超深软基护岸结构在后方堆载高附加应力条件下的侧向变形，解决超深软土中护岸结构的安全性差、海域占用面积大等问题，很好地克服现有技术所存在的弊端。
