摘要:
提出采用截面参数分析法与有限元数值模拟相结合的方法对钢波纹管受力变形进行计算分析.将截面参数分析法所得计算结果与美国ASTM规范对比,验证了截面参数分析法的有效性.根据截面参数计算结果将钢波纹管道等效为实壁管道,并在此基础上对应不同工况建立有限元数值模型,进一步研究了钢波纹管道在填土施工过程中的变形与内力特性,总结了其力学性能与填土高度、管道规格的对应关系和钢波纹管道设计中的建议管道规格.最终根据钢波纹管道施工现场工况,对管周土体竖向土压力及管道环向应变进行计算,通过与现场实测数据对比,验证了该方法模拟钢波纹管管土相互作用的有效性.研究表明所提出的钢波纹管分析方法简便准确,并能很好地再现钢波纹管道的力学特性.
Abstract:
A combined method of the sectional characteristic analysis and numerical simulation is proposed to analyze the mechanical and deformation properties of corrugated steel pipes. The analysis results were in agreement with ASTM specifications, which proved the effectiveness of the sectional characteristic analysis. By equivalently transforming corrugated pipes to solid wall pipes based on the sectional characteristic analysis results, a series of finite element models corresponding to different field conditions were established to investigate the deformation and internal force of corrugated steel pipes as well as the relationship between mechanical properties and specifications of pipes in the construction process. Also, recommended specifications of corrugated steel pipes were put forward. Finally, the results of the numerical model were compared with the measured vertical earth pressure around pipes and hoop strains of pipes in the field, demonstrating that the combined method is effective for corrugated pipe design. The proposed analysis method is convenient and can well reflect the mechanical properties of corrugated steel pipes.
