［摘要］古建筑平移工程中多采用滚轴作为移动装置，易产生平移偏位，且移动过程中需人工调整滚轴位置，增加了辅助工作时间。通过对滚轴支撑系统、轴承支撑系统、滚珠支撑系统进行顶推力比对试验分析发现，在相同荷载下，轴承支撑系统的顶推力与滚轴、滚珠支撑系统的顶推力相比较小，从而降低了建筑移位时的加速度，且定向性能好。对轴承支撑系统的滚动摩擦特性及受压承载力进行试验研究，结果表明，轴承支撑系统的顶推力与荷载之比F/N值较为平稳，其极限受压承载力远远高于额定载荷，安全度高、可操作性好，尤其适用于结构自重较小的平移工程。

Abstract: The rollers are used as moving device in all the ancient buildings translocation projects. The rollers are easy to deviate in the translocation and need adjustment of position artificially, which increases the auxiliary working time. Comparing tests were carried on the thrust force among the roller supporting system, bearing supporting system and the ball supporting system. Results show that under the same load, the thrust force of the bearing supporting system is smaller than the thrust force of roller supporting system and ball supporting system. Bearing supporting system can reduce the acceleration in the translocation and has excellent directional property. Tests of rolling friction characteristics and compressive capacity of the bearing supporting system were carried out. Results show that the F/N values of the bearing supporting system are reposeful and the ultimate bearing capacity is much higher than the load rating. Bearing supporting system is safe, well operable and suitable for the small weight translocation project.

Keywords: ancient buildings translocation; moving system; roller supporting system; characteristics of rolling friction
