［摘要］對(duì)于承受較大水平荷載的樁基工程應(yīng)考慮豎向與水平荷載聯(lián)合作用對(duì)樁基性狀的影響。根據(jù)樁基可能承受的豎向水平荷載聯(lián)合作用情況，建立與原型具有相似規(guī)律的模型試驗(yàn)方案，研究樁基受豎向水平荷載組合作用下的受力與變形特性。試驗(yàn)結(jié)果表明，豎向荷載對(duì)水平受荷樁的水平位移與樁身彎矩均有一定程度的不利影響，研究成果對(duì)實(shí)際工程具有參考價(jià)值。

Abstract:Influence of vertical and horizontal loads should be considered when the pile foundations were subjected to large horizontal loads. According to the possible working conditions of the actual piles, a simplified model test was established on the similar rules with the original model. The stress and deformation of the pile under vertical and horizontal loads were investigated by model tests. Some useful conclusions for research and engineering practice were achieved from the model tests. The results show that vertical load has a negative influence on the displacement and moment of the pile under horizontal load.

Keywords:vertical load; horizontal load; combined effect; single pile; model test
