RESEARCH ON EFFECT OF WATER LEVEL FALL ON VERTICALLY LOADED SINGLE PILE
-
摘要: 通过有限元分析,研究地下水位下降对摩擦桩和端承桩的受力性状,揭示出桩侧负摩阻力的发展规律,并对下拉荷载产生的原因给予分析,提出设计中应预先考虑水位变化影响的重要性,由降水引起的桩顶附加沉降和下拉荷载应进行详细计算。Abstract: The working behavior of single piles with vertical loading is studied by FEM methods.The negative skin friction of piles and pull-down on piles are analyzed.The importance of considering water level change is stressed in pile design.Both the additional settlement and pull-down load on piles due to water level fall should be evaluated.
