【摘要】：我国有非常悠久的桥梁史,而石拱桥是我国桥梁史上技术最成熟的一类桥型。随着科技发展与进步,近年来,交通事业迅猛发展的大背景下,大量新的桥型不断涌现。尽管如此,石拱桥不失其独特地位,以用的材料比较节省,结构比较巧妙,强度比较高等特点被广泛应用着,发挥着其独特的作用。随着年代的增加,大部分石拱桥在自然作用和人类活动的影响之下出现较多病害,影响了正常的使用。因此,我们对石拱桥保护的研究一定要积极进行。目前已存在的石拱桥保护理论,在实际应用中缺乏加固后的效果监测。本文通过对实际工程的研究,探讨出石拱桥保护加固过程中的具体措施和方法,并对实际施工保护后的效果进行监测。本文首先阐述石拱桥的发展历史、形成和演变过程、建造的独特工艺,再系统分析石拱桥的常见病害,并在此基础上,提出具体的针对性的加固保护措施。通过对会通桥、问津桥工程实地调查,结合周边环境现状,找出其存在主要病害并分析分析出产生的原因。在此基础上,进行详尽加固保护计划的制订。本文根据石拱桥的形成、建造工艺和受力特点,制定出结构健康监测方案,得到桥体基本数据,分析桥体的沉降、倾斜、动力特性等,得出石拱桥结构健康报告,为进一步的保护提供科学依据。本文所提出的加固保护及健康监测方案对运河沿岸其他石拱桥保护研究具有一定的借鉴意义。
[Abstract]:There is a very long history of bridges in China, and stone arch bridge is the most mature type of bridge in the history of bridges in our country. With the development and progress of science and technology, in recent years, with the rapid development of transportation, a large number of new bridge types are emerging. In spite of this, the stone arch bridge is widely used and plays its unique role because of its unique position, saving in material, ingenious structure and high strength. With the increase of age, most stone arch bridges appear more diseases under the influence of natural action and human activities, which affect their normal use. Therefore, we must actively study the protection of stone arch bridge. The existing theory of stone arch bridge protection lacks the effect monitoring after reinforcement in practical application. In this paper, the concrete measures and methods in the process of protection and reinforcement of stone arch bridge are discussed through the study of practical engineering, and the effect of actual construction protection is monitored. In this paper, the history, formation and evolution of the stone arch bridge, the unique process of construction, and then the common diseases of the stone arch bridge are systematically analyzed, and on this basis, concrete measures for strengthening and protecting the stone arch bridge are put forward. Based on the field investigation of Huitong Bridge and Wenjin Bridge Project and the current situation of surrounding environment, the main diseases are found out and the causes are analyzed. On this basis, the detailed reinforcement and protection plan is worked out. According to the formation, construction technology and stress characteristics of stone arch bridge, this paper formulates the structural health monitoring scheme, obtains the basic data of the bridge body, analyzes the settlement, tilt and dynamic characteristics of the bridge, and obtains the structure health report of the stone arch bridge. To provide scientific basis for further protection. The reinforced protection and health monitoring scheme proposed in this paper can be used for reference in the study of the protection of other stone arch bridges along the canal.
