近20年来,由于国家的大力支持和市场的旺盛需求,我国钢结构发展迅猛,被称为建筑行业的“朝阳产业”。各类钢结构企业应运而生,但专业技术人员相对匮乏,工程质量控制水平低下,以至于在一些钢结构工程中出现了严重的技术经济不合理现象,甚至造成了许多工程质量事故,损失惨重。为了保证建筑质量,提高建筑水平,要加强对建筑物的检测,无损检测既实现了对建筑物的检测,同时保证了建筑物的质量。
In the recent 20 years, due to the strong support of the country and the strong demand in the market, the steel structure in our country has been developing rapidly. It is called the “sunrise industry” in the construction industry. Various types of steel structure enterprises came into being, but the relative lack of professional and technical personnel, engineering quality control level is low, so that in some steel structures there have been serious technical and economic irrationality, and even caused a lot of engineering quality accidents, heavy losses . In order to ensure the construction quality and improve the building level, it is necessary to strengthen the testing of buildings. Nondestructive testing not only realizes the testing of buildings but also ensures the quality of buildings.
