土工织物是国外七十年代兴起的一种新型材料。它具有良好的耐久性和较高的抗拉强度,能承受巨大变形,设计载荷作用下的徐变较小而且耐腐蚀,是理想的护坡保护材料。由于施工方便,造价低廉,并具有排水、过滤、防渗、隔离、提高承载能力和增加整体强度等多种功能,故被世界上许多国家广泛采用。法国使用土工织物始于1970年左右,在韦拉克诺斯坝的上游堆石护坡和坝址排水层周围铺设土工织物,提高了大坝的整体性,减少了水对护坡的冲刷。在日本和苏联,土工织物已有多年的使用经验,在河堤、海岸和公路的护坡上铺设土工织物,有效地保护了护面。在德
Geotextiles are a new type of material that emerged in the seventies abroad. It has good durability and high tensile strength, can withstand tremendous deformation, creep under the design load is small and corrosion-resistant, is the ideal slope protection material. It is widely used in many countries in the world due to its convenient construction, low cost, and various functions such as drainage, filtration, seepage prevention, isolation, increase of carrying capacity and increase of overall strength. The use of geotextiles in France began around 1970 and laid geotextiles around the rockfill revetments upstream of the Veracruz Dam and around the drainage layer of the dam site to improve the integrity of the dam and reduce erosion of the slope by water. In Japan and the Soviet Union, geotextiles have been used for many years to provide geotextiles on embankments, coastal and roadside slopes, and effectively protect the surface. In Germany
