项目名称公路护栏立柱埋深无损检测技术研究与设备开发获奖等级三等奖公路护栏立柱埋入深度不足直接影响整体防撞强度。2004年12月,中央电视台《焦点访谈》栏目以“路基下的隐患”曝光了山西某高速公路护栏立柱埋入深度严重不足问题,引起了社会公众和交通行业的广泛关注。国内外一直缺乏有效的护栏立柱埋深无损检测手段,传统的桩基小应变完整性测试技术在实际的立柱埋深测试中也难以实现。此前,行业标准中只规定使用
Project Name Road fence Column depth of nondestructive testing technology research and equipment development Third prize of the award-winning highway Fence embedding depth of less than a direct impact on the overall impact strength. In December 2004, the “Focus Interview” section of CCTV exposed the serious imbalance in the buried depth of a highway guardrail pillar in Shanxi with the sub-roadway hidden dangers, which aroused widespread concern of the public and the transportation industry. At home and abroad, there is a lack of effective means of non-destructive testing of buried column depths. The traditional testing method of small strain integrity of pile foundations is also difficult to achieve in actual column depth testing. Previously, only the provisions of the industry standard use
