以承台+3根桩体系为例,研究了该体系含1根倾斜桩对体系承载力的影响情况,分析时以实际工程数据为基础,结合数值模拟手段,对单根桩3种倾斜方向及6种倾斜程度进行了计算分析。结果显示,1根桩倾斜并未影响承台+3根桩体系的承载力,仅当倾斜程度较大时体系承载力略有降低,由于桩体的倾斜承台均发生了水平向位移,但是在正常使用条件下位移量不大。各种工况计算结果显示,桩身弯矩的分布特征明显,得到了桩身最大弯矩位置、反弯点位置等,且弯矩值均未超过桩身设计弯矩值,说明文中研究的体系不会发生弯曲破坏。
Taking the pile foundation +3 pile system as an example, the influence of one inclined pile on the bearing capacity of the system is studied. Based on the actual engineering data and the numerical simulation method, three inclined directions And six kinds of tilt were calculated and analyzed. The results show that the bearing capacity of one pile does not affect the bearing capacity of the platform +3 pile system. The bearing capacity of the system is slightly lower only when the inclination is larger. Because of the horizontal displacement of the inclined bearing platform, Under normal conditions of use is not large displacement. The calculation results of various working conditions show that the distribution characteristics of pile bending moment are obvious, the maximum bending moment position and the bending moment position of pile body are obtained, and the bending moment values do not exceed the bending moment of pile design. The system will not bend damage.
