加筋土是在土中加拉条、纤维或网状材料,利用它们与土的摩阻力来抵抗土受到的张力和剪力,从而增强土的稳定性,提高土的抗剪强度。这项新技术是1963年法国工程师享利·达维尔发明的。它的原理是:土壤能够承受压力,而不能承受拉力,在自重和外力作用时容易破碎,但如果在土中埋入称为拉筋的加强材料,土体受剪切破坏向临空面膨胀挤出时,由于土 Reinforced earth is a galvanized strip, fiber or mesh material in the soil, and uses the frictional resistance between them and the soil to resist the tension and shear force received by the soil, thereby enhancing the stability of the soil and improving the shear strength of the soil. This new technology was invented by Henry Davier, a French engineer in 1963. Its principle is: the soil can withstand pressure, and can not withstand the tensile force, easy to break in the role of self-weight and external force, but if embedded in the soil called reinforcement material reinforcement, soil shear expansion damage to the surface of the expansion When extruding, due to soil
