第一节加筋土技术的发展情况加筋土是法国工程师亨利、维达尔(Henrivibal)在1963年发明的,法语称为“TerreArméc”。在欧洲普及后,加拿大、日本、美国等相继引进,现已被世界上许多国家的土木工程师所采用。大多首先应用于公路或铁道建筑中。用带状加筋或纤维材料加固土的做法并不是最近才有的。一些动物和鸟类早已用这种方法建筑它们的巢穴。几百年以前,人们已经在土坯砖中加草筋,以提高土坯的强度,通过泥沼地带的道路往往用柴排铺在填土下面。用砂袋或树枝加固堤岸则是至今常用的一种加筋土类型。亨利、维达尔的成就是把加筋土技术提高到一个新的阶段,使之能够经济地应用到大型 Section 1 Development of Reinforced Earth Technology Reinforced earth was invented in 1963 by the French engineer Henrivi and Henrivibal and in French in the name of Terre Arméc. After being popularized in Europe, Canada, Japan, and the United States have been introduced one after another and are now being used by civil engineers in many countries in the world. Most of them are first used in road or railway construction. Reinforcing soils with band reinforcement or fiber materials is not a recent practice. Some animals and birds have long used this method to build their nests. A few hundred years ago, people had added grass ribs to adobe bricks to increase the strength of the adobe. Roads that passed through the quagmire zone were often covered with firewood below the fill. Reinforcing embankments with sand bags or branches is a type of reinforced soil commonly used so far. The achievements of Henry and Vidal are to increase reinforced earth technology to a new stage, so that it can be economically applied to large-scale
