摘要
土工合成材料作为新型的软土地基处理技术,在工程领域大量应用。但是土工合成材料的种类和规格很多,材料的性能也有所不同,所以需要建立可计算出各种土工合成材料所受载荷的方法模型。土工合成材料的单桩承载力由材料的抗拉强度和工程性质决定,考虑将土工材料和碎石桩的相互作用作为已知变量,以及碎石桩所承受的上部载荷,就可以推导出土工合成材料所受到的约束拉力与所在土体围压的桩身强度的关系。通过莫尔-库仑理论和布西内斯克理论推导得到了土工合成材料受的约束拉力沿深度的分布,为土工合成材料碎石桩的设计提供计算依据。
Geosynthetic material,as a new type of soft ground treatment technology,has been used in a large number of engineering fields.However,there are many kinds and specifications of geosynthetics,and the properties of the materials are also different,so a method model is needed to calculate the load of various geosynthetics.Geosynthetic materials of the single pile bearing capacity is determined by the tensile strength and the engineering properties of materials,through the take an examination of the geotechnical materials and gravel pile interaction as the known variables,considering the gravel pile on the upper load,can be derived from synthetic materials by the constraints of the tension and the strength of soil in the confining pressure of pile body.In this paper,the distribution of constrained tension along the depth of geosynthetics is obtained by using Mohr-Coulomb theory and Boussineske theory derivation,which provides a calculation basis for the design of geosynthetics gravel pile.
