桥梁施工作业面长,线型较复杂,层次高低不一,施工中很容易发生几何位置差错(特别是弯桥),造成梁架不上去或严重偏离轴线等重大工程质量事故,延误工期、浪费资金、后果十分严重。据统计,造成10万元以上经济损失的重大工程事故中,有近半是因几何位置差错所至,因此究其原因,采取控制措施,杜绝差错尤为必要。笔者列举事故实例,分析其原因,提出解决办法,供有
Long bridge construction work, more complex lines, different levels, the construction is prone to geometric location errors (especially curved bridge), resulting in the beam does not go up or seriously deviate from the axis and other major engineering quality accidents, delays in construction, waste Funds, the consequences are very serious. According to statistics, nearly half of the major engineering accidents that caused the economic losses of over 100,000 yuan were caused by errors in geometric positions. Therefore, it is necessary to take control measures to eliminate mistakes. The author lists examples of accidents, analyzes its causes, and proposes solutions to them
