摘    要:用现场静载试验的方法,利用预埋钢筋计和土压力盒,进行了高速铁路路基声屏障桩基础在竖向荷载作用下的桩身应力和桩底反力的测试。重点分析声屏障桩基础在荷载作用下的沉降量和桩身内力。结果表明:对于声屏障的桩基础,采用试验时的桩长、桩径和桩身混凝土,桩基的承载力很大,桩顶荷载主要由桩周土的侧摩阻力来承担,并分析了此类桩基础承载力的影响因素,为今后进一步改进声屏障桩基础的设计提供了可供参考的试验数据和经验积累。

关 键 词:声屏障   桩基础   竖向静载试验   侧摩阻力   桩端阻力

Abstract:By use of on-site static load test method, the pile body stress and the pile bottom reaction, which arise on sound barrier pile foundation under vertical load along subgrade of high-speed railway, were tested by setting embedded reinforcement meter and earth pressure cell, wherein the settlement of the sound barrier pile foundation and the internal force of the piles were the concerns. The results show that, for the sound barrier pile foundation, the pile length, pile diameter and pile concrete in the test are used, and the pile foundation has large bearing capacity with the working load on pile top borne by the side friction force of the soil around the pile. In addition, the factors influencing bearing capacity of such pile foundation were analyzed, which provides test data for reference and experience accumulation so as to further improve the design of sound barrier pile foundation in the future.
