高等级公路深厚软土地基工后沉降控制板承式路堤技术
摘要：
本发明公开了一种高等级公路深厚软土地基工后沉降控制板承式路堤技术，在软土地基与路堤填土之间设置钢筋混凝土板作为硬壳层，混凝土板厚度为300mm~1000mm；混凝土板可位于地表之上，或部分埋入地基，或全部埋入地基；混凝土板底部可铺设垫层；路堤填土的坡比小于1:1.5，坡面采用土工布包裹；混凝土板靠近路堤边缘两侧可设置低挡墙，低挡墙底部与混凝土板固定在一起，整体变形。本发明可消除路堤边缘和路堤中心的差异沉降，避免了路基产生纵向裂缝，路堤边坡不会失稳破坏，减小了路堤填土的补偿土方量。与排水固结法相比，本发明可有效地减小工后沉降。与复合地基法相比，本发明造价低。本发明工期短，只考虑填土工期，特别适用深厚软土地基上的一般路段。
摘要（英）：

The invention discloses a plate supporting type embankment structure for post-construction settlement controlling of a deep soft soil foundation on a high-grade highway. A reinforced concrete plate is arranged as a hard shell layer between the soft soil foundation and embankment earth filling, the thickness of the concrete plate ranges from 300 mm to 1000 mm, the concrete plate can be located above the earth surface or be partly embedded into the foundation or be fully embedded into the foundation, a cushion layer can be arranged at the bottom of the concrete plate, the slope ratio of the embankment earth filling is smaller than 1:1.5, the slope surface is wrapped by geotextile, a low retaining walls can be arranged on each of two sides of the concrete plate, the two sides of the concrete plate are close to the edges of the embankment, the bottom of each low retaining wall is fixed with the concrete plate, and overall deformation is achieved. By means of the plate supporting type embankment structure for the post-construction settlement controlling of the deep soft soil foundation on the high-grade highway, differential settlement of the embankment edges and the embankment center is eliminated, longitudinal cracks of the foundation are avoided, an embankment side slope can not lose stability and not be damaged, and compensation earth volume of the embankment earth filling is decreased. Compared with drainage concretion methods, by means of the plate supporting type embankment structure, post-construction settlement is effectively reduced. Compared with composite foundation methods, the plate supporting type embankment structure is low in cost. According to the plate supporting type embankment structure for the post-construction settlement controlling of the deep soft soil foundation on the high-grade highway, construction time is short, construction time of the earth filling is merely considered, and the plate supporting type embankment structure is particularly applicable to ordinary road sections on the deep soft soil foundation.
