摘　　要：新建跨河桥梁基础会对汛期堤防渗流场产生一定影响,造成堤防的渗透破坏,需采取相应防治与补救措施。总结了现有跨堤桥梁不同的防渗处理措施及适用情况,选取马鞍山公铁大桥作为典型案例进行了稳定渗流和非稳定渗流数学模型计算,分析了涉河桥梁建设对堤防渗流场的影响和不同防渗措施的效果,提出了不同防渗处理措施的适用情况。The foundation of newly constructed bridge across river will affect the seepage field of the embankment during flood season and cause infiltration damage to the embankment.Corresponding preventive and remedial measures are essential.We summarize current seepage control measures for embankment-crossing bridges and their applicability.Taking the Ma'anshan Highway-Railway Bridge as a case study,we conducted mathematical computations of the steady and unsteady seepage.Through analyzing the impact of river-crossing bridge construction on the seepage field of embankment and the effect of different seepage control measures,we propose the applicability of different seepage control treatment measures.
