摘　　要：桥梁,作为交通网络的关键元素,其功能在于跨越诸如江河湖泊与深谷峭壁等天然障碍,从而实现“化险为夷”的连接效果,确保道路的畅通无阻。桩基础在桥梁结构中扮演着核心角色,尤其在桥梁建设朝着大跨度、高负荷的方向发展时,其展现出的显著优势使其成为了首选的基础解决方案。这些优势包括:强大的承载能力、较低的沉降、便利的施工过程以及对复杂地质环境的适应性,这使得桩基础能够有效地支撑起桥梁的重量,确保结构的稳定性和耐久性。在承受上部结构传递的荷载时,桩基系统不仅要确保具有足够的承载力,还必须有效管理沉降,以满足上部结构对于变形量的严格限制。因此,深入探究桩基础的竖向承载性能变得极为重要。Bridge,as a key element of the transportation network,functions to cross the natural obstacles such as rivers,lakes and deep valleys,so as to realize the connection effect of"saving the danger"and ensure the smooth flow of the road.Pile foundation plays a core role in the bridge structure,especially when the bridge construction is developing towards the direction of large span and high load,and its significant advantages make it the preferred foundation solution.These advantages include:strong carrying capacity,low settlement,convenient construction process,and adaptability to the complex geological environment,which enable the pile foundation to effectively support the weight of the bridge and ensure the stability and durability of the structure.When bearing the load transferred by the superstructure,the pile foundation system should not only ensure that it has sufficient bearing capacity,but also effectively manage the settlement to meet the strict limit of the deformation of the superstructure.Therefore,it is very important to explore the vertical bearing performance of pile foundation deeply.
