钢架拱桥的检测与评估

随着我国公路建设规模不断增加,大跨径和钢结构桥梁的大量使用,在摸索和不断创新中桥梁理论和施工工艺新技术、新方法不断被推广使用。大跨径桥梁受益于钢结构的较大刚度,因此也被广泛应用于现代桥梁中。桥梁技术的不断进步要求桥梁检测技术也需要根据桥梁特点进行不断创新,检测和评估技术的好坏直接关系到桥梁的使用寿命和桥梁的使用安全性。对日常常用钢结构进行分析,以实际检测为例,通过对实际应用中的常规钢结构桥梁病害检测分析来说明检测评估的基本方法,根据检测相应结果对桥梁进行评估。

Detection and Evaluation of Steel Frame Arch Bridge

With the increasing scale of highway construction in China, large-span and steel structure bridges are widely used. In the exploration and continuous innovation, the bridge theories and construction technologies, and new technologies and new methods are constantly popularized and used. Long-span bridges are widely used in modern bridges because of large stiffness based on steel structure. With the development of bridge technologies, the bridge detection technologies also need to be continuously innovated according to the bridge characteristics. The qualities of detection and evaluation technologies are directly related to the service life and safety of the bridges. The daily common steel structures are analyzed. Taking an actual detection as an example, the basic method of detection and evaluation is explained by analyzing the disease detection of conventional steel structure bridges in practical application. The bridge is evaluated according to the corresponding detection results.
