Foundation treatment method and artificial foundation
The invention provides a foundation treatment method which comprises the following steps: (1) digging an original foundation soil body within a certain range and depth from the upper layer of a silt soil field according to the requirement of the bearing capacity of the foundation; (2) mixing the excavated original foundation soil body with a curing agent to form solidified soil; (3) a gravel cushion layer is laid at the pit bottom where the original foundation soil body is excavated; and (4) the solidified soil is laid on the gravel cushion layer to form a solidified soil layer, and the solidified soil layer is rolled and compacted. Therefore, the gravel cushion layer is laid between the solidified soil layer and the soil layer, moisture discharged by the soil layer can be absorbed, a water film or a mud film is prevented from being formed between the soil layer and the solidified soil layer, the friction force between the soil layer and the solidified soil layer is increased, and the contact between the soil layer and the solidified soil layer is firmer; and the bearing capacity of the treated foundation is further improved.
本发明提出了一种地基处理方法，该地基处理方法包括：(1)根据地基承载力需求，在淤泥土场地的上层挖掉一定范围和深度的原地基土体；(2)将挖除的所述原地基土体和固化剂混合，形成固化土；(3)在挖除所述原地基土体的坑底铺设砂石垫层；(4)将所述固化土铺设在所述砂石垫层的上方形成固化土层，碾压压实。由此，在固化土层和泥土层之间铺设砂石垫层，能够吸收泥土层排出的水分，防止在泥土层和固化土层之间形成水膜或泥浆膜，增加泥土层和固化土层之间的摩擦力，使泥土层和固化土层之间的接触更牢固，进一步提高所处理后地基的承载力。
