摘要
分析了输电塔中基础连梁对基础水平位移的影响,研究了连梁尺寸对基础水平位移的影响规律。运用有限元软件,建立了2个典型桩—土—输电塔有限元耦合模型,结合有无连梁和改变连梁尺寸,探讨了有无连梁和连梁尺寸对基础水平位移影响规律。研究结果表明,在桩—土—输电塔中设置连梁,可明显减小群桩和单桩基础水平位移,且钢连梁直径越大、厚度越大,基础水平位移越小。
The influence of foundation coupling beams on horizontal displacement of foundation in transmission tower is analyzed,and the influence law of coupling beam size on horizontal displacement of foundation is studied.Two typical finite element coupling models of pile-soil-transmission tower are established with the finite element software.The influence of the existence of coupling beams and the size of coupling beams on the horizontal displacement of foundation is studied respectively when there are coupling beams,there are no coupling beams and when the size of coupling beams changes.The results of research show that the horizontal displacement of pile group and single pile foundation can be significantly reduced by setting up coupling beams in pilesoil-transmission towers.And the larger the diameter and thickness of steel coupling beams are,the smaller the horizontal displacement of foundation is.
