【摘要】：系杆拱桥已经在我国的实际工程中得到大量应用。对已建成的系杆拱桥进行检测评定,是确保桥梁寿命期内运营安全的重要保障。本文参考了国内外相关规范、标准及研究成果,研究了系杆拱桥的检测、评估及其计算机系统实现问题。系杆拱桥检测系统主要运用C++语言,基于MFC框架和Google Earth编码实现。本文研究的主要内容及主要成果有以下四点。1、检测单元划分及其计算机程序实现桥梁检测单元是桥梁检测过程中需要独立对待的基本构件。检测单元的划分是桥梁现场检测细致、全面、不会疏漏的前提条件。同时也是计算机编程中信息传递、信息共享和数据管理的必需条件。本文研究了系杆拱桥一般性的检测单元划分方法和编码方式,在单元划分的基础上对其的检测内容、检测方法进行了分类介绍。论文还利用计算机编码实现了检测单元的划分。2、吊杆和系杆两大部件的检测流程和方法在吊杆和系杆两大部件病害分析的基础上,本文研究这两大部件的一般性检测流程和方法。总结了柔性吊杆及短吊杆的索力计算公式,及检测的流程。论文结合Midas有限元分析,提出基于关键点位移变化的系杆断裂检测方法。3、系杆拱桥关键部位病害的长期跟踪监测方法本文对系杆拱桥的裂缝、吊杆、系杆、墩台腐蚀、沉降位移、拱肋外鼓变形等关键部位病害进行了整理,并且针对每一类病害,阐述了长期监测的方法。4、系杆拱桥检测信息集成及其计算机程序实现本文针对系杆拱桥,建立了桥梁的成桥信息、定期检测、养护管理、维修工程、监测数据等数据信息的整体分类方法,详细规定了每部分信息的定义和集成要求。利用计算机编码实现了系杆拱桥的检测信息集成,便于大量检测数据信息的分析、处理和存储。5、系杆拱桥技术状况评估及其计算机程序实现本文主要依据了国内的桥梁检测规范,并结合系杆拱桥的结构特点制定了系杆拱桥的技术状况评估流程。利用计算机编码实现了基于检测信息的桥梁技术状况评定。论文将计算机技术运用于系杆拱桥的检测评估领域,为该桥型的实际管理工作提供帮助和便利。
[Abstract]:Tied arch bridge has been widely used in practical engineering in China. The inspection and evaluation of the completed tied arch bridge is an important guarantee to ensure the safety of the bridge during its lifetime. This paper refers to the relevant codes at home and abroad. Standard and research results, the detection, evaluation and computer system realization of tied arch bridge are studied. C language is mainly used in the inspection system of tied arch bridge. Based on MFC framework and Google Earth coding implementation. The main contents and main achievements of this paper are as follows. 1. Detection unit partition and its computer program to realize bridge detection unit is the basic component which needs to be treated independently in the bridge detection process. The detection unit division is the bridge field inspection meticulous and comprehensive. It is also a necessary condition for information transmission, information sharing and data management in computer programming. This paper studies the general detection unit partition method and coding method of tied arch bridge. On the basis of the unit partition, the detection content and detection method are introduced. In addition, the computer coding is used to realize the division of the detection unit. 2. The detection flow and method of two parts of suspender and tie rod are based on the analysis of the disease of the two parts. This paper studies the general testing flow and method of these two parts, summarizes the calculation formula of cable force of flexible and short suspenders, and the flow of detection. The paper combines with Midas finite element analysis. Based on the change of key point displacement, this paper puts forward the method of inspecting the fracture of tie bar based on the change of key point displacement, and the long-term tracking and monitoring method of the disease of the key part of tied arch bridge. This paper deals with the cracks, suspenders, tie bars, abutment corrosion and settlement displacement of tied arch bridge. For each kind of disease, the method of long-term monitoring. 4, the information integration of tethered arch bridge detection and its computer program to achieve this paper for tied arch bridge. The whole classification method of bridge information such as bridge completion information, regular detection, maintenance management, maintenance engineering, monitoring data and so on is established. The definition and integration requirements of each part of the information are specified in detail. The detection information integration of tied arch bridge is realized by computer coding, which facilitates the analysis, processing and storage of a large number of detection data information. Technical Evaluation of tied Arch Bridge and its realization by computer Program this paper mainly bases on the bridge inspection code in China. Combined with the structural characteristics of tied arch bridge, the evaluation flow of technical condition of tied arch bridge is established. The bridge technical condition evaluation based on detection information is realized by computer coding. In this paper, the computer technology is applied to tie arch bridge. In the field of testing and evaluation. To provide help and convenience for the practical management of the bridge type.
