建筑物整体移位抬升工程中的牵引力试验研究

Traction experimental investigation of building's integer shift

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。

Coefficient of rolling friction in building＇ s integer shift is an important factor about safety and economy, and there are some construction experience and interior experiment about this, but few locate experiment. It obtained and analyzed the data of outside force of an integer shift engineering through the locate experiment using transducer and strain gate and deduced the rolling friction coefficient of this type of integer shifting. The conclusion provides responsible design basis of this type of integer shifting.
