在建筑物整体移位工程中,滚轮的滚动摩擦系数是一个关键的影响因素,虽然目前已有一些施工经验值和实验室模型实测值,但是在实际施工过程中对该值的测定却很少。应用应变仪、传感器等试验设备,通过在建筑物整体移位工程的现场与建筑物的移动同步进行的牵引力测定试验,得到了该建筑物整体移位工程的外加动力试验值,并对其进行分析研究,进而求得了针对该工程所使用的滚轮与轨道装置的滚动摩擦系数,在理论上对以往的施工经验给予了验证和补充,为今后该种工程的实施提供了可靠的设计参考依据。
Rolling friction coefficient is a key factor in the overall displacement of the building. Although there are some construction experience values and laboratory model actual values, there are few measurements of this value in the actual construction process . By using the testing equipment such as strain gauges and sensors, the applied dynamic test value of the whole displacement project of the building was obtained through the traction force test carried out synchronously with the movement of the building at the site of the overall displacement project of the building, and carried out Then, the rolling friction coefficient of roller and track device used in this project is obtained, which verifies and supplements the previous construction experience theoretically, which provides a reliable design reference for the future implementation of this kind of project.
