土工布被称之为继钢材、水泥、木材之后的岩土工程中的第四种新型建筑材料,国外工业化国家使用土工布已有许多年了,在道路修筑、铁路路基加固、排水工程、海岸防护和土墙斜坡的支承方面,借助于土工布,使设计和施工更为经济简便,尤其是在道路和铁路路基养护成本上,土工布的使用,使这项工作大为节省。 Geotextiles are called the fourth new type of building materials in the geotechnical engineering after steel, cement, and wood. Geotextiles have been used in foreign industrialized countries for many years, in the construction of roads, reinforcement of railway subgrade, drainage works, and the coast. With regard to the protection and protection of earth slopes, the use of geotextiles has made the design and construction more economical and convenient, especially in the maintenance costs of roads and railway subgrades. The use of geotextiles has greatly saved this work.
