The invention relates to the technical field of constructional engineering, and discloses a construction foundation treatment method for a region with a liquefied soil bearing stratum, which comprises the following steps: 1) digging an upper foundation pit earthwork; (2) vacuum preloading treatment is conducted on the inner bottom face of the foundation pit, and then quantitative loading is applied; (3) a plurality of foundation piles are constructed downwards on the inner bottom face of the foundation pit, and the pile tops of the foundation piles do not exceed the inner bottom face of the foundation pit; 4) digging out bearing stratum soil bodies among the foundation piles; and (5) a reinforced cushion layer is additionally arranged between the foundation piles. According to the method for treating the building foundation in the area with the liquefied soil bearing layer, when the building foundation in the area with the liquefied soil bearing layer is treated, the liquefied soil layer in the foundation pit is replaced and filled with gravel, then the reinforced cushion layer is additionally arranged, and the foundation is compacted and compacted, so that the compactness change of the foundation is small when the foundation is vibrated, and the liquefaction phenomenon cannot occur, and therefore, the construction efficiency is improved. By the adoption of the scheme, the purpose of improving the construction quality can be achieved.
本发明涉及建筑工程技术领域，且公开了一种具备液化土持力层地区的建筑地基处理方法，包括以下步骤：1)挖上层基坑土方；2)在基坑内底面进行真空预压处理，然后进行施加定量堆载；3)在基坑内底面向下施工多个基桩，所述基桩的桩顶不超过基坑的内底面；4)将各所述基桩之间的持力层土体挖出；5)在所述基桩之间加设加筋垫层。该具备液化土持力层地区的建筑地基处理方法，在处理具备液化土层地区的建筑地基时，将基坑内的液化土层换填为砂石，再加设加筋垫层，对地基进行夯实和挤密地基，使得该地基在受振动时密实程度变化较小，不会出现液化现象，因此，采用本发明中的上述方案能够实现提高施工质量的目的。
