摘要
将高强度预应力管桩(PHC管桩)抽象化成压缩弹簧与剪切弹簧模拟其工作机理,通过分析闸底板压应力分布及各桩的轴力及位移,从而优化桩基布置,尽量使长桩布置在竖向荷载大的部位,短桩分散布置在荷载较小的部位,这样可以减小闸底板竖向变形,保证大闸结构安全。
The high strength prestressed pipe pile(PHC) is Abstracted into compression spring and shear spring for simulating its working mechanism,and then the stress distribution on the bottom slab of the sluice as well as the axial force and displacement of all the piles concerned are analyzed,so as to optimize the layout of the pile foundation,i.e.trying to arrange longer pile on the location with larger vertical load and the shorter one on the location with smaller load.In this way,the vertical deformation of the bottom slab can be decreased and the structure safety of the sluice can be ensured as well.
