摘要
依托连云港港徐圩港区预制厂扩建工程,利用数值分析手段研究真空预压对桩基应力应变的影响,得出单桩桩顶位移随距加固边界距离减小而增大的变化规律以及桩基受力模式,并提出通过地梁连接桩基形成框架结构,减小抽真空对单桩水平位移影响的工程措施。
In the Lianyungang Port Xuwei District prefabrication factory extending project, the numerical analysis is employed to research the influence on the stress and strain for the pile foundation by vacuum preloading. It is found that for each single pile, the displacement of the top increases as the distance away from the boundary of the stiffened soil decreases, and the stress pattern of the pile foundation is obtained. In addition, to reduce the impact of the vacuum on the horizontal displacement of each single pile, a frame structure that connects the footing beam to the foundation of piles is proposed.
