林区公路桥梁承载能力的分析与评定

THE ANALYSIS AND EVALUATION OF THE BEARING ABILITY OF THE HIGHWAY BRIDGE IN FOREST ZONE

公路桥梁承载能力的分析与评定,在桥梁建设中是一个极其重要的问题。根据大量的桥梁调查和试验研究资料,并结合桥梁的技术状况与实际工作状态,从桥梁检算与荷载试验两方面对现有桥梁承载能力进行了论证与分析。提出承载能力鉴定系数K作为桥梁结构承载能力的评定标准,对于大量的林区公路桥梁的综合评定具有很大的实用价值与经济效益。

It is a very important problem that the anlysis and evaluation of the bearing ability of the highway bridge in the engineering fields. Basing on much information of the bridge investigation and the test and combining them with the technical and real working condition, this paper has carried on the analysis and evaluation about the bearing ability of the bridge from two aspects of calculation and the load test in the bridge. The paper has put for ward the identification coefficient K of the bearing ability as the evaluation standard in the bearing ability of the bridge structure. The identification coefficient K has the precise physical concept and the specific applied limit, and it has the greater applied value and the economic benefit for the comprehensive evaluation of many highway bridges in forest zones.
