青藏铁路乌马塘至古荣高烈度地震区桥梁设计

Bridge design in highly seismic region in Qinghai-Tibet railway

以青藏铁路乌马塘至古荣的铁路桥梁设计为例,介绍了其线路、地质、地层岩性等具体情况,提出了高烈度地震区桥涵设计的原则及简化的抗震计算法,对高原和高烈度地震区铁路桥梁设计有一定借鉴作用。

Taking the railroad bridge design in Qinghai-Tibet railway as example the conditions of route, geology, stratum and lithologic characters are introduced for bridge design. The bridge and culverts design principle in highly seismic region and simplified calculation method of earthquake resistance are proposed, which provide valuable references for bridge design in plateau and highly seismic region.
