摘　　要：根据某引桥工程进行综合设计分析,引桥工程由陆上段和水上段组成:引桥陆上段120m,采用混凝土挡墙、冲孔灌注桩、T梁等构件组成。引桥水上段:圆筒沉箱基础+墩台结构段共1349m,钢管桩+墩台结构段共518m,预留转换平台大型沉箱1件。引桥工程水上段沉箱上部结构现浇混凝土工程主要分为沉箱盖板、立柱、上引桥墩3部分。对相关设计参数进行验证并逐一分析。According to a comprehensive design analysis of a certain approach bridge project,the approach bridge project consists of an onshore section and an underwater section:the onshore section of the approach bridge is 120m long and consists of concrete retaining walls,punched cast-in-place piles,T-beams,and other components.The above water section of the approach bridge:the cylindrical caisson foundation+pier and abutment structure section is 1349m in total,the steel pipe pile+pier and abutment structure section is 518m in total,and one large caisson for the reserved conversion platform is reserved.The cast-in-place concrete project for the upper structure of the caisson in the water section of the approach bridge project is mainly divided into three parts:the caisson cover plate,the column,and the upper approach bridge pier.This article verifies and analyzes the relevant design parameters one by one.
