摘　　要：采用荷载效应比较法对重力式桥台结构进行了研究,通过对重力式桥台截面强度、台后等代土压力、地基承载力以及基底稳定性的验算与分析,得出相应通行权判定结论。In this paper,the load effect comparison method is used to study the gravity abutment structure,By checking and analyzing the cross-section strength of gravity abutment,the equivalent earth pressure behind the abutment,the bearing capacity of foundation and the stability of foundation,the conclusion of determining the corresponding traffic weight is obtained.

关 键 词：大件运输 重力式桥台 通行能力判定
