【摘要】：交通体系作为支撑和促进社会经济发展的重要先决条件,在社会经济发展中,扮演着极为重要的角色,桥梁在路网中更是起到了核心作用,其技术状况直接决定了道路体系的通行能力。加强桥梁管理、消除安全隐患,对保障人民群众生命财产安全具有极其重要的意义。论文针对国道212线广元嘉陵江三号桥为工程实例进行了危桥管理及其检测、维修加固研讨,以期为类似公路危病桥的运营养护提供相关经验。本文主要研讨的内容如下:1、研究如何针对普通地方公路桥梁中危病桥的管理建立一个安全可控的管理体系,以该桥为例,研究普通地方公路类似桥梁的检测、维修加固的运用方法。2、危病桥梁管理是安全管理的第一个关键环节,研究管养单位针对初步认定为四、五类危桥的管理措施。3、技术状况评定作为确定桥梁真实通行能力、抗洪能力的具体措施,是危病桥管理的重要手段。本文探讨了通过分层综合评定与四、五类危病桥梁单项控制指标评定之间互相结合的方法,对构件、部件进行综合评定之后,分别再对桥面系、上部结构和下部结构进行评定,最后进行桥梁总体技术状况的评定。4、探讨对检测发现的各类结构病害,应采取病害处治的方法,结合实例桥提出的维修加固方案。
[Abstract]:As an important prerequisite for supporting and promoting social and economic development, transportation system plays an extremely important role in social and economic development, and bridges play a central role in the road network. Its technical condition directly determines the capacity of the road system. It is of great significance to strengthen the bridge management and eliminate the hidden dangers of safety to ensure the safety of people's life and property. In this paper, the management of dangerous bridge and its inspection, maintenance and reinforcement are discussed for the engineering example of Guangyuan Jialingjiang No. 3 Bridge of National Highway 212 line, in order to provide relevant experience for the operation and maintenance of similar highway critical bridge. The main contents of this paper are as follows: 1. To study how to establish a safe and controllable management system for the management of dangerous bridges in common local highway bridges, taking the bridge as an example, to study the detection of similar bridges in common local highways. 2. The management of critically ill bridges is the first key link in safety management. As a concrete measure to determine the real capacity and flood control capacity of bridges, the evaluation of technical condition is an important means of bridge management. This paper discusses the method of combining stratified comprehensive assessment with the evaluation of single control index of four and five kinds of critically ill bridges. After comprehensive evaluation of components and components, the bridge deck system, superstructure and substructure are evaluated respectively. Finally, the overall technical status of the bridge is evaluated. 4. The method of disease treatment should be adopted to detect and find various structural diseases, and the maintenance and reinforcement scheme of the bridge should be taken in combination with an example.
