摘要
土工合成材料具有应用广、性能可靠、重量轻、运输方便、施工简捷、耐久性好等优点 ,在提高河道整治工程的稳定性、堤防工程的截渗加固和险情抢护等方面得到广泛应用。在土体中埋入具有高拉伸强度的土工合成材料 ,通过筋材与周围土体界面间摩擦阻力的应力传递 ,从而约束土体的拉伸应变 ,减少土体变形 ,增加土体的模量 ,改善土体的受力情况 ,提高土体的承载力和结构的稳定性。
Composite earthwork materials feature such advantages as wide application, reliable performance, light weight, convenient transportation, quick construction and long endurance. They are widely applied in enhancing stability of river improvement works, seepage cutoff and consolidation and wrecking of the embankment works. Through friction force between steel bars and the earth around them, the composite earthwork material planted inside earth blocks can restrain deformation, increase the module of the earth blocks, improve the conditions of forces imposed on the blocks so increasing load capacity and the structure stability.
