【 摘 要 】

The large span spatial steel is used in chop manufactory of the Chengdu integrated circuit manufacturing project. Because of the complex construction conditions, high altitude cumulative slip construction is adopted to ensure the installation quality and construction requirements of the structure. The vertical displacement, bearing synchronicity and key bar stress during the sliding process are monitored in same time. The smooth implementation of the slip construction scheme is guaranteed in that way. In addition, the monitoring data are analyzed, and the reliability of the sliding construction technology is demonstrated, which provides reference for the standardization of the slippage construction of the large span steel roof in China..
