摘要
以修建工业厂房对桥梁桩基稳定性的影响为工程背景,采用ANSYS有限元分析方法研究新建建筑物修建对桥梁桩基结构内力的影响,结果表明,荷载作用下桥梁桩基的压应力增量最大值发生在Y方向(竖直方向),为0.65MPa;将数值模拟结果与监控量测数据进行对比分析发现,荷载作用下桥梁桩基变形比监控量测竖向位移小0.003mm,说明建立的数值模型及其参数取值合理,可用于评价新型建筑物对桥梁桩基结构的影响。
Aimed at the influence of build industrial workshop on bridge pile foundation stability,the paper used the finite element analysis software ANSYS to analyze the internal force of pile foundation of bridge structure construction of new buildings. The results shows that the loads maximum compressive stress increment of bridge pile foundation 0. 65 MPa is in Y direction（ vertical direction）; by comparison of numerical analysis and monitoring data analysis,the load on pile foundation of bridged formation monitoring and measuring the vertical displacement is less than 0. 003 mm,which can illustrate the value of the finite element model and its parameters are reasonable,can be used to evaluate the influence of new building on the bridge pile foundation.
