摘　　要：据说息壤是一种可以自生自长的土,远古的先民们曾用它防治洪水。对这种传说中的岩土材料进行了考据,根据河狸坝与我国古代的治河工程,指出所谓息壤应当是古代人们利用草、木、竹、石、土创造出来的加筋土,用以拦截阻挡洪水。秦汉时期称为茨防,宋代称为埽工。回顾了我国土工加筋及其在河工中应用的长远历史,指出土工合成材料在保护环境、保护资源和我国经济可持续发展中应用的广阔前景。It is said that ＂ Xi-rang ＂ is a sort of soil which can grow continuously by itself. So, it is used in flood control in ancient China. In this paper, a textual research on the geotechnical material is made. It is pointed out that ＂ Xi-rang ＂ is the reinforced earth used in flood control projects. It was named ＂ Ci-fang ＂ in Qin and Han Dynasties and the fascine works in Song Dynasty. The beaver dam and the history of soil reinforcement in China are reviewed. The application of geosynthetics in hydraulic engineering is introduced. It is concluded that geosynthetics will get a vast prospect of application in environmental protection and natural resources protection in sustainable economic development in China.
