土工合成材料加筋土（GRS）整体桥梁的开发，以克服传统类型的桥梁通常包括一个简单的支持梁固有的几个严重问题（或主梁）、钢筋混凝土桥台和未加固回填土的方法：即桥台后面有隆起物，施工/维护成本高;支座和回填土抵抗地震和海啸荷载的稳定性低;大型桥台结构; GRS整体桥的建造方法如下：首先建造一对GRS墙和一个中间墩（或多个墩）（如有必要）;其次，通过在用土工格栅钢筋包裹的墙面上现浇混凝土，建造轻型钢筋全高刚性（FHR）面板;最后，两端与FHR面板顶部集成的连续梁。阐述了GRS整体桥的发展背景。报告了2012年和2014年完成的前四个病例。
Geosynthetic-reinforced soil (GRS) integral bridge was developed to overcome several inherent serious problems with conventional type bridges typically comprising a simple-supported girder (or girders), RC abutments and approaches of unreinforced backfill: i.e. high construction/maintenance cost while bumps immediately behind the abutments; a low stability of the bearings and backfill against seismic and tsunami loads; massive abutment structures; needs for piles etc. A GRS integral bridge is constructed by constructing firstly a pair of GRS walls and an intermediate pier (or piers) if necessary; secondly lightly steel-reinforced full-height-rigid (FHR) facings by casting-in-place concrete on the wall face wrapped-around with the geogrid reinforcement; and finally a continuous girder with both ends integrated to the top of the FHR facings. The background of the development of GRS integral bridge is explained. The first four case histories, completed in 2012 and 2014, are reported.
