Construction method for shallow layer of deep soft foundation low embankment
The invention discloses a construction method for a shallow layer of a deep soft foundation low embankment, which comprises the following steps: when the filling height of the embankment is in a range of 0-0.5 m, a replacement filling method is adopted for treatment, and the treatment widths of the two sides of the embankment are at least respectively increased by 2.0 m; when the filling height of the embankment ranges from 0.5 m to 2.0 m, cement mixing piles are adopted for treatment, and the treatment widths of the two sides of the embankment are at least increased by 2.0 m to 1.0 m respectively; when the filling height of the embankment ranges from 2.0 m to 3.0 m, CFG pile treatment is adopted, and the treatment widths of the two sides of the embankment are at least increased by 1.5 m to 1.0 m. For the low embankment condition, a deep soft foundation low embankment shallow layer treatment scheme is adopted, damage to the roadbed soil body structure is reduced, and then the purposes of reducing the settlement amount and reducing settlement earthwork are achieved.
本发明公开了种用于深厚软基低路堤浅层的施工方法，包括以下步骤:当路堤填筑高度在0‑0.5m范围时，采用换填法处理，路堤两侧处理宽度至少应各增加2.0m；当路堤填筑高度在0.5‑2.0m范围时，采用水泥搅拌桩处理，路堤两侧处理宽度至少应各增加2.0m‑1.0m；当路堤填筑高度在2.0‑3.0m范围时，采用CFG桩处理，路堤两侧处理宽度至少应各增加1.5m‑1.0m本发明对于低路堤情况，采用深厚软基低路堤浅层处理方案，有利于减小对路基土体结构性的破坏，进而达到减小沉降量、减少沉降土方的目的。
