软基具有天然含水量高、孔隙比大、压缩性高、抗剪强度低等不良特性,冲填土层和淤泥质土层分布厚度大,采用土工格栅进行地基处理,即可使基础荷载通过垫层产生应力扩散、均化地基应力、减少不均匀沉降、约束地基的侧向变形、提高地基承载力和稳定性,又能缩短工期、节省投资,在围堤工程中得到广泛应用。
Soft foundation has the characteristics of high natural water content, large void ratio, high compressibility, low shear strength and so on. The thickness of red soil and muddy soil is large. Geogrids are used for foundation treatment to make the foundation load Stress diffusion through cushion layer, averaging the stress of foundation, reducing uneven settlement, restraining lateral deformation of foundation, improving bearing capacity and stability of foundation, shortening construction period, saving investment and being widely used in embankment project.
