摘要
文中以某公路桥梁工程为例,在明确施工现场的土层类型及关键参数后,进行千斤顶、锚桩横梁反力装置等设施的配置,设计单桩静载试验方案,从沉降、桩身轴力、桩侧摩阻力等多个方面综合分析被测桩基础的承载特性.结果表明,该桩基础的承载力达标,得出的静载试验检测数据对管控桩基础施工质量具有重要意义.
Abstract
Taking a highway bridge project as an example,after defining the soil layer type and key parameters of the construction site,the con-figuration of facilities such as jack and anchor pile beam reaction device is carried out,the static load test scheme of single pile is designed,and the bearing characteristics of the tested pile foundation are comprehensively analyzed from many aspects such as settlement,pile axial force and pile side friction resistance.The results show that the bearing capacity of pile foundation is up to the standard,and the static load test data obtained is of great significance to control the construction quality of pile foundation.
