介绍了日本近35年来铁路、公路及其他主要是铁路用各种土工合成材料加筋土结构的发展和建设情况。在20世纪80年代，开发了具有全高刚性（FHR）面板的GRS挡土墙（RW）。在加固回填土和地基土充分变形后，将FHR面板与加固层牢固连接。20世纪90年代初，开发了GRS桥台，用于支撑FHR面板顶部的简支梁一端。在21世纪初，GRS整体桥被开发出来，它在结构上将连续梁的两端集成到一对GRS RW的FHR面板的顶部。截至2019年6月，这些GRS结构的总墙长约为185公里，没有出现任何问题。FHR饰面的使用、FHR饰面的分阶段施工和GRS整体桥的结构一体化是GRS结构技术发展的三大突破。
The development and construction of various types of geosynthetic-reinforced soil (GRS) structures for railways, roads and others, mainly for railways, for the last 35 years in Japan is described. In the 1980s, GRS retaining wall (RW) with full-height rigid (FHR) facing was developed. The FHR facing is constructed firmly connected to reinforcement layers after the reinforced backfill and subsoil has deformed sufficiently. In the early 1990s, GRS Bridge Abutment supporting one end of a simple girder at the top of the FHR facing was developed. In the early 2000s, GRS Integral Bridge was developed, which structurally integrates both ends of a continuous girder to the top of the FHR facings of a pair of GRS RWs. The total wall length of these GRS structures became about 185 km by June 2019 with no problematic case. The use of FHR facing, the staged construction of FHR facing and the structural integration for GRS Integral Bridge are the three major breakthroughs for the development of these GRS structure technologies.
