摘　　要：本文以博斯坦水库工程中的跨河桥为研究对象,该桥梁承载运料及弃渣的交通任务,由于地处山区且属于工程内部桥梁,其区域地震活动较强,荷载频率高,行驶密度较集中,为保证工程使用安全,本文采用桥梁专业分析软件对承载能力进行了计算,验证上下部结构的安全稳定性,从而验证桥梁的使用安全性。通过采用madis civil桥梁计算软件,运用荷载组合,分别提取了桥梁上部结构承载能力进行了计算,经上部结构计算成果分析和下部结构抗震验算结果分析,得出跨河桥上部结构计算均能满足规范要求,经抗震验算桥梁下部结构各项强度、位移均满足规范要求。本文成果验证了博斯坦水库工程跨河桥的安全稳定性,为桥梁设计提供了理论依据,后续设计过程中,可直接运用本文成果进行设计。In this paper,the author took a bridge crossing a river for Bernstein reservoir project as the research object.The bridge function is transporting building materials and construction wastes.Because it is located in the mountainous area and belongs to an internal bridge for the reservoir project,in the region earthquake activity is stronger,the load frequency is high,and the traffic density is relatively concentrated,in order to ensure the safety of the bridge project,the author used the bridge professional analysis software on bearing capacity calculation,to verify the safety stability of the upper and lower structure,so as to verify the safety of the bridge.By adopting Madis Civil bridge calculation software,using the load combination,the author respectively calculated bearing capacities of upper structures for the bridge,through the analysis on calculation results for upper structures and earthquake-resistant checking calculation results for lower structures,obtained that the calculation results of both upper and lower structures for the bridge are all satisfy with the demand of relative specification,through earthquake-resistant checking calculation,the strengths and displacements of lower structures of the bridge are all also satisfy with the demand of relative specification.In this paper,the author checked the whole stability of the bridge,provided the theoretical basis for bridge design.In bridge design afterwards,the results obtained in this paper can be directly used.
