市场经济的快速发展,道路桥梁建设项目逐渐增多。科学技术水平的创新,也使得道路桥梁建设中的科技化水平逐渐提升,各项性能也得到明显提升。此次提出关于多点桁架结构与深水群桩基础抗震性能关系的分析研究,利用反向振动提高基础刚度。研究结果表明,多点桁架组合结构对深水桥梁群桩基础的抗震性能有明显改善。 With the rapid development of market economy, road and bridge construction projects are gradually increasing. The innovation of science and technology has also led to a gradual increase in the level of science and technology in the construction of roads and bridges and a marked improvement in various performances. This paper presents the analysis of the relationship between the multi-point truss structure and the seismic performance of deep-water group pile foundation, and uses reverse vibration to improve the foundation stiffness. The results show that the multi-point truss composite structure of deep-water bridge group pile foundation seismic performance has been significantly improved.
