摘要/Abstract

摘要： 为解决冲刷引起的桥梁墩台基础受损,进而引起承载能力降低并危及运营安全的问题,以某重载铁路桥墩洪水冲刷病害为工程背景,采用理论分析和现场试验相结合的方法,提出一套考虑墩身和基础共同加固的增补桩基法+基础加固法的组合技术方法,制定分步实施方案,并应用在实际工程中。结果表明:加固后,单桩承载力、墩顶位移和桩侧土压力等静力指标明显改善,桥墩和桥跨结构横向振动幅值较加固前显著降低,桥墩横向自振频率增大5倍,墩台基础刚度和承载能力显著提高。

Abstract: In order to prevent destruction of pier foundation caused by flood scouring which will further affect bearing capacity and operation safety, a set of technical method combining supplementary pile foundation and foundation reinforcement method was proposed based on theoretical analysis and field test of flood scour disease of a heavy load railway pier. Then, a step-by-step implementation plan was drafted and applied in practical projects. The results show that static indexes, such as bearing capacity of single pile, displacement of pier top and earth pressure at pile side, are improved obviously after reinforcement, transverse vibration amplitude of bridge pier and span structure is markedly lower, and lateral vibration frequency of pier increases 5 times. Foundation stiffness and bearing capacity of pier and abutment are improved significantly.
