纤维加筋土是按一定比例将很细的纤维丝或纤维网与土料充分拌合而成的一种土工复合材料。网状纤维可以与周围土体相互咬合形成三维结构。在工程性质方面,纤维加筋能有效提高土体的抗剪抗压能力。本文在室内试验的基础上对纤维加筋土的抗剪强度进行研究,研究成果如下:不同含量的纤维网片均匀地掺入粉土,利用直接剪切试验测定试件抗剪强度,得到纤维网片的最优含筋率为0.2%。
Fiber reinforced soil is a certain proportion of very fine fiber or fiber mesh and soil material fully mixed from a geocomposite. Mesh fibers can interbedded with the surrounding soil to form a three-dimensional structure. In terms of engineering properties, fiber reinforcement can effectively improve the soil anti-shear compression capacity. In this paper, based on the laboratory tests, the shear strength of fiber-reinforced soil was studied. The research results are as follows: Different content of the fiber mesh was uniformly mixed into the silt, the shear strength was measured by direct shear test to obtain the fiber The best web containing reinforcement 0.2%.
