摘要
针对高大井塔要求层高较高的特点,探讨了筒体式钢筋混凝土井塔壁板稳定的重要性和主要影响因素,研究了轴压比与稳定性之间的关系,通过对"一字形"、"T形"壁板稳定性分析,给出了在不同厚度和层高下的稳定轴压比允许值,提出了各种情况下的合理壁板厚度,并通过合理设置壁柱可以减少楼层数量实现大层高和减小壁板厚度,对减轻井塔的地震作用、节约投资有着积极的意义。
As the tall hoist tower requires big storey height, the paper discusses the significance and major influence factors of siding stability of cylinder reinforced concrete hoist tower, and studies the relationship between axial compression ratio and stability, through the stability analysis of " - " shape and "T" shape siding, offers the permissible value of stable axial compression ratio under different siding thickness and storey height; through reasonable design of pilaster, the number of floors can be reduced to achieve big storey height and small siding thickness, so as to alleviate the seismic action of hoist tower, and save investment.
