国外加筋土结构物发展简介法国工程师亨利·维达尔(Henri Vidal)在做三轴剪切试验时,发现掺有纤维材料的土抗剪强度提高了好几倍,于是,维达尔于1960年首次提出了加筋土概念,1963年公开发表了加筋土研究成果和加筋土结构设计理论,1966年将这项理论付诸实践:在法国～意大利A_5号高速公路建成了世界上第一座加筋土挡墙,同年,维达尔在法国土力学会上发表加筋土研究报告,相继获得专利。此后,这项施工 Abroad Reinforced Earth Structure Development Brief introduction French engineer Henri Vidal did three-axis shear tests and found that the shear strength of soil mixed with fiber materials increased several times, so Vidal first time in 1960 Put forward the concept of reinforced earth, publicly published in 1963, reinforced earth research results and reinforced soil structure design theory, put this theory into practice in 1966: in France - Italy A5 highway built the world’s first Reinforced earth retaining wall, the same year, Vidal published in the French soil Society reinforced soil research report, have been patented. Since then, this construction
