摘　　要：针对桥台台前土压力计算存在争议的问题,研究土弹簧模拟桩土作用下台前和台后填土压力对超高肋板式桥台的影响,以实际工程为例,采用Midas Civil有限元分析软件对超高肋板式桥台进行数据建模,得出高墩桥台填土压力结构安全风险计算的可靠性参数,通过施工监测校验研究结果。In view of the controversial problems in the calculation of earth pressure in front of abutment,the paper studied the influence of pre-platform and post-platform filling pressure on ultra-high ridged slab abutments under the pile-soil action condition simulated by soil spring,adopts Midas Civil finite element analysis software to conduct data modeling for the ultra-high ridged slab abutments based on the actual project. The paper obtains reliability parameters of high pier abutment filling pressure structure safety risk and verifies the study results through construction monitoring.
