土工合成材料详解(国外英文资料) Geosynthetic materials Earthwork composite materials: applied to geotechnical engineering materials, made from polymers. One, type: 1) earthwork network: flat network structure of composite materials, which are compressed by synthetic materials or synthetic resin. 2) earthwork grille: the polymer materials are stretched to form the open mesh and the high strength of the plane network. 3) earthwork pattern bag: a continuous (or single) bag of woven fabric. 4) earthwork fabric: flat surface material for water transmission. Spinning: two sets of parallel filaments or yarn interwoven in certain ways; Non-spinning: a fabric that is aligned or undirected by a filament or fiber. 5) earthwork composite drainage materials: non-woven earthwork fabric, earthwork net, earthing film or different shape of the material core composite and the soil works drainage materials; 6) geotechnical (net) pad: thermoplastic resin as raw material, formed by extrusion, stretching and winding, and on the contact each other mutual confluence, to high modulus of base layer at the bottom of the three-dimensional gauze pad. Scope of application: The synthetic materials of earthwork are suitable for strengthening weak foundation, accelerating the consolidation of soil and improving soil strength. For the construction of roadbed and soil, prevent the turning and sinking of the roadbed; It is used to strengthen the slope of the embankment and make the slope of the structural slope increase and compacted. To strengthen and strengthen after the retaining wall; It is used for drainage and drainage. The geotechnical engineering application is more of the earthwork fiber. Construction points: Reinforced embankment: 1) when making synthetic materials, the direction of high intensity is perpendicular to the direction of the embankment. The surface of the laying base should be flat, and the surface of the surface will be removed from the surface of the material, and the maximum size of the ma
