摘要
研究通过引入拉压杆件理论,对公路桥梁的下部结构进行系统性的优化设计.首先分析了传统桥梁设计中存在的问题.通过建立数学模型,将桥梁下部结构简化为一系列的拉压杆件.通过对比分析优化前后的结构性能,验证了基于拉压杆件模型的优化设计方法的有效性.研究为公路桥梁下部结构设计提供了一种新的思路和方法,对于推动桥梁工程的技术进步具有重要意义.
Abstract
This article systematically optimizes the substructure design of highway bridges by introducing the theory of tension and compression members.This article first analyzes the problems existing in traditional bridge design.By establishing a mathematical model,the lower structure of the bridge is simplified into a series of tension and compression members.By comparing and analyzing the structural performance before and after optimization,the effectiveness of the optimization design method based on the tension and compression member model is verified.This study provides a new approach and method for the design of the substructure of highway bridges,which has important theoretical and practical significance for promoting technological progress in bridge engineering.
