资料简介： Abstract: The paper is presented cases of failures of steel scaffolds damaged by vehicle strikes during the construction of new viaducts over the upgraded A-18 motorway in Poland. After several vehicle strikes into the scaffold structures their damaged components were no longer serviceable (considering the safety of the construction works being carried out). This put the contractor to additional expenses connected with the replacement of the damaged scaffold. The causes and consequences of the failures are given and the necessary solutions adopted in the considered cases – whereby the traffic situation significantly improved – are described. Moreover, it is proposed to increase the minimum vertical clearance required during the building or repairs of bridge structures.

本文提出了在波兰的A - 18高速公路建设高架桥期间钢脚手架由车辆碰撞下引起的损坏。在不同车辆若干次碰撞后脚手架里面损坏的地方将不能修复（考虑到施工的安全性）。这让承包商承担了更换已损坏的脚手架的额外开支。要给出损坏的原因和后果，并给出必要的解决方案 - 即交通状况显着改善 - 进行了描述。此外，在桥梁结构建设或修理期间，还建议提高最低垂直净空要求。关键词：脚手架故障，车辆碰撞，损坏组件，新事物，高架道路建筑，高速公路的A - 18
