某建筑物平移工程顶推动力影响因素研究

Influencing Factors Research of Jacking Force in the Building Translation Project

以某办公楼平移工程为例,对建筑物平移工程中首次顶推动力大于之后的顶推动力的原因进行了探究和分析,得出了首次顶推力会在建筑物上部产生较大的剪应力,对建筑物安全有一定影响的结论;通过对影响因素的分析,得出首次顶推动力数值的大小与粘结力的大小、下轨道梁钢板上杂质是否清除干净、滚轴和钢板的变形、下轨道梁的变形等因素有关,并给出了减小首次顶推动力的解决措施。

Based on an office building translation project as an example in this paper,it is analyzed that the first jack-ing force is greater than the later j acking force in the building translation proj ect.It is concluded that the j acking force for the first time can produce larger shear stress in the upper buildings,which can affect the building’s safety.By the a-nalysis of the influencing factors,it is obtained that the size of the jacking force in the first time is related to the size of the cohesive force,the impurities on the lower track’s steel,the deformation of the rollers,the steel plates and the track beam.It gives some measures to reduce the jacking force for the first time.
