摘　　要：本研究对钢箱梁箱室积水的成因与其对桥梁受力的影响进行了分析,提出排水系统的故障为积水的形成创造了条件,进而使用ANSYS软件对连续钢箱梁桥箱室积水前后的受力情况进行对比分析。分析结果显示,在箱室满水情况下,桥梁承受最大正弯矩与负弯矩处的顶、底板应力增大2.6%~26.6%,最后对箱内积水的治理措施进行了总结。This paper analyzes the causes of water accumulation in the steel box girders and its impact on the forces exerted on the bridge.It proposes that the malfunction of the drainage system may lead to water accumulation.Subsequently,the ANSYS software was used to conduct a comparative analysis on the stress conditions of a continuous steel box girder bridge before and after water accumulation.The analysis results show that under the condition of the box chamber being full of water,the stress on the top and bottom plates at the locations of the maximum positive and negative moments increases by 2.6%to 26.6%.Finally,the measures for dealing with water accumulation in the steel box girder are summarized.
