土工布是一种用于土木工程的新型纤维制品,在和其它土建材料一起组成的一个结构、一个工程、一个系统中具有渗透性的织物。土工材料具有较高的拉伸强度、延伸性和整体性:有良好的水力特性,能起到较好的防渗、反滤作用:稳定性好、耐用、使用寿命长。因此广泛用于水利、交通、建筑等工程方面。目前世界上以聚丙烯和聚对苯 Geotextile is a new kind of fiber product used for civil engineering. It is a structure, an engineering, and a system that has permeability with other civil engineering materials. Geotextiles have high tensile strength, extensibility and integrity: they have good hydraulic properties and can play a good role in anti-seepage and anti-filtering: they have good stability, durability and long service life. Therefore, it is widely used in water conservancy, transportation, construction and other projects. At present, the world uses polypropylene and poly-p-phenylene
