摘要
以宁波象山湾疏港3标段工程为研究背景,对工程中30m后张法预应力混凝土节段T梁进行研究.介绍了该工程的项目概况、节段T梁构造特点和预制成桥施工工艺流程,研究预制节段简支T梁的受力特征.通过有限元软件Midas建立模型,对节段预制简支T梁的力学性能进行检算分析.分析结果表明,30 m节段预制T梁结构受力与变形满足相关规范要求,为高速公路预制T梁技术提供借鉴与参考.
Abstract
The study focuses on the 30-meter post-tensioned precast concrete segmental T-beams within the Ningbo Xiangshan Bay Channel Dredging and Harbor Improvement Project,Section 3.The project overview,structural characteristics of the segmental T-beams,and the precast and bridge assembly construction process are introduced.The research delves into the mechanical behavior of the precast segmental simply supported T-beams.Through the utilization of the finite element software Midas,a model is developed to conduct a thorough analysis of the mechanical performance of the precast segmental simply supported T-beams.The obtained results reveal that the structural response and deformations of the 30-meter segmental precast T-beams meet the relevant specifications.This study provides valuable insights for the advancement of precast T-beam technology in highway construction,offering a foundation for reference and application.
