The working characteristics of a pile group containing raked piles are analyzed with a simplified model by means of finite element method.
采用有限元方法，通过简化算例分析了带斜桩的群桩基础的工作特点。Therefore, researches of the subject of post grouting pile group foundation settlement characteristics are conducted for this paper.
故本文针对后注浆群桩基础沉降性状这一课题展开相关研究工作。Pile foundations are often used to transfer loads of bridge through soft soil to stronger bearing strata at depth.
桥梁通常是透过桩基础穿越软弱土层，将荷载传递到可承载的深层土层。The door frame type bracing structure is one type of bracing structure which is developed and formed on the basis of double-row piles.
门架式围护结构是在双排桩基础上发展形成的一种围护结构型式，具有较大的侧向刚度，可以有效地限制其侧向变形，不必设置内支撑。Steel tube pile foundation was controlled with neither settlement , nor pre-compaction, and supervised in a whole during construction.
钢管桩基础以零沉降控制，免预压，施工中整体监控。In crowd- pile foundation design, the general idea thinks all the load bearing by piles and not considering the interpile soil bearing load.
群桩基础设计通常不考虑极间土承担荷载，认为荷载全部由极承担。The pile head under load and the soil around the pile are produced on the basis of friction piles while load covered in the pre-field case.
同时在预制场满布荷载的情况下，桩顶承受荷载，桩基础周围土体均对桩基础产生了摩阻力。And also by analysis on bearing capacity of pile, this paper present some structural measures of this kind of pile foundations.
并通过对桩基的受力分析，给出该类桩基础的一些构造措施。The present invention discloses one kind of composite bridge caisson pile foundation and its reverse construction process.
本发明公开了一种桥梁沉箱复合桩基础及其逆作建造方法。
