摘　　要：本文介绍了土工合成材料在天津大港海堤中心的应用情况，着重进行了土工布作用机理的分析，并编制了计算机程序进行堤坡稳定性计算。分析表明，在软土地基上铺设土工布后，能起到加速地基排水团结、约束地基侧向位移、扩散荷载、隔离堤体拉力破坏区和堤基剪切破坏区贯通的作用。由于这些作用的结果，提高了地基承载能力，同时也改善了地基的变形特性。This paper gives the introduction in detail to application of geotextile in Dagang sea wall.It analyzed geotextile work mechanism,forthermore,aProgram is compiled to coaculate stability of slope.According to the analysis,geotextiles play an important role in accelerating drainage and consolidation of earth,in keeping lateral displacement within the bounds,in spreading pressure at base of foundation,and in separating pull failure zone of enbankment fromshear failure zone of foundation,As the result of these action,the bearing capcity of foundation and the soil deformation are improved.By the general lim it equilibrium method,although the enhance of security caused by geotextiles is a little(about 3.5%),the practical effactivity is obvious.The reason of the difference between theory and practice probably is without considering deformation modulus of geotextile.
