Heightening and thickening reinforcing structure for embankment in super-thick soft soil layer area, preventing soil squeezing and controlling settlement
The invention discloses an ultra-thick soft soil layer area dike heightening and thickening anti-soil-squeezing and settlement-controlling reinforcing structure which comprises mixing pile treatment areas, reinforcing piles, geogrids, heightening and thickening areas and a ballast platform, the mixing pile treatment areas are located in soil bodies on the two sides of a dike, the reinforcing piles are arranged in the mixing pile treatment areas, and the geogrids are arranged in the heightening and thickening areas. The geogrid is laid on the surface of the dike and the surface of the mixing pile treatment area and extends into the earth surface on the outer side of the mixing pile treatment area, the heightening and thickening area is arranged at the upper end of the dike and covers the geogrid, and the ballast platform is at least arranged at the upper end of the mixing pile treatment area and at least covers the geogrid on the surface of the mixing pile treatment area. The mixing pile treatment area carries out full treatment on the two sides of the dike, the soil property characteristics of the two sides are changed, the soil strength and the deformation resistance are improved, the geogrids can improve the combination tightness of the heightened and thickened area and the dike, differential settlement is prevented, the additional stress of the deep layer is reduced, and the work integrity of the whole dike is ensured.
本发明公开了一种超厚软土层地区堤防加高培厚的防挤土控沉降加固结构，包括：搅拌桩处理区、加固桩、土工格栅、加高培厚区、压载平台，搅拌桩处理区位于堤防两侧的土体中，加固桩设置于搅拌桩处理区中，土工格栅铺设于堤防表面、搅拌桩处理区表面并延伸至搅拌桩处理区外侧的地表中，加高培厚区设置于堤防上端并将土工格栅覆盖，压载平台至少设置于搅拌桩处理区上端并至少将搅拌桩处理区表面的土工格栅覆盖。搅拌桩处理区对堤防两侧进行满处理，改变两侧土性特征，提高土体强度与抗变形能力，土工格栅可以提高加高培厚区与堤防结合的紧密性，同时防止差异沉降，减少深层的附加应力，确保整个堤防的工作整体性。
