摘　　要：为了尽量降低地铁车站施工对既有地面交通的影响,盖挖法是经常采用的一种施工方法,其中构建一个稳定、可靠的临时路桥系统是盖挖法施工中的一个关键环节,这方面目前我国尚没有专门的设计规程加以约束。结合某地铁车站盖挖法施工的实际工程,就临时路面板的设计计算、军便梁体系的设置参数以及军便梁与围护结构的相互作用等方面展开计算分析,获得了诸多有益的结论,同时为盖挖法临时路桥体系设计计算提供了一般原则。In order to minimize the influence of subway station construction on the existing ground traffic, the cover - excavation method is widely used. In this case, a keypoint is to build a stable and reliable temporary road and bridge system, q＇here is no specific design specification in this field. Combining with a project of metro station constructed by cover-excavation method, the design calculation of temporary pavement slab, the parmnent configuration of military beam system, the interaction of military beam and enclosure structure are studied. Many useful conclusions are obtained to provide general principles of design calculation for temporary road and bridge system by cover-excavation method.
