The conventional type bridge, which comprises a girder supported with a pair of cantilever-type abutments via shoes and unreinforced backfill, tends to be massive while the seismic stability is relative low and the long-term maintenance cost is relatively high. To alleviate these problems, a new type bridge (called GRS integral bridge) is proposed. The new type bridge comprises a continuous girder integrated to a pair of abutments without using shoes while the backfill is reinforced with a geosynthetic reinforcement connected to the abutment. By performing a series of model static and dynamic loading tests and numerical analysis, it is confirmed that this new type bridge is much more cost-effective exhibiting substantially higher seismic stability, long-term higher performance and higher constructability than the conventional type bridge.

传统桥梁是由一对悬臂式桥台通过鞋和未加筋的回填体支撑的主梁组成的，它往往体积大，地震稳定性较低，长期维护成本较高。为了解决这些问题，提出了一种新型的GRS积分桥。新型桥梁包括一个连续梁集成到一对不使用鞋的桥台，而回填土是用土工合成钢筋连接到桥台加固。通过一系列的模型静、动荷载试验和数值分析，证实了这种新型桥梁比传统桥梁具有更高的抗震稳定性、更高的长期性能和更高的可施工性。
