混凝土拱桥剩余承载能力有限元分析

Analysis of residual bearing capacity of concrete arch bridge in service by finite element method

根据结构分析的有限元方法、桥梁设计规范和桥梁承载能力评定规程,在桥梁病害调查和构件力学性质现场检测的基础上,通过建立能反映桥梁实际病害的结构分析力学模型,对某运营中的混凝土拱桥主要受力构件进行必要的验算与分析,评估了结构构件和桥梁的剩余承载能力,对该桥的加固与维修提供了技术依据.

The residual bearing capacity of arch ribs of a reinforced concrete arch bridge in service is checked and analyzed based on the finite element method,design codes of bridges and the specification for capacity test and assessment of highway bridges of China,considering the typical disease distribution in the bridge structure and the test data about mechanical properties in site in the structural analysis model,and the member and structural behavior are assessed and the conclusions are drawn in the paper,whic...
