3 . the simplification and simulation of group piles of foundation of continuous rigid frame bridge has been introduced 对大跨径连续刚构桥中多采用的群桩基础的简化模拟做了介绍。
Based on the numerical model , fortran is used for programming both the single pile and groups pile in this paper 根据所建立的分析模型，本文用fortran语言编制了相应的单桩和群桩的计算程序。
On the basis of the project - experimental research on large - scale pile group foundation of lizigou large - span bridge , this paper is finished 本文结合课题“李子沟特大桥超大型群桩基础试验研究”完成。
Finally , comparisons are made between theoretical and measured displacement . in general , satisfactory agreement is found 最后通过实测的结果和单桩及群桩解析解的结果对比，精度基本上能够满足工程需要。
There is less research about bartered pile and pile group . in this paper the " generalized elastic theory " is proposed to solve the problem 目前对于斜桩单桩和有斜桩群桩承载特性的研究，还鲜有文献报道。
Based on calculation and analysis of b8 bridge pile cluster foundation , upper and lower structure configuration can be adjusted 摘要通过对b8桥群桩基础的布置、计算及分析，提出下部结构要和上部结构相协调的观点。
Furthermore , a mass of numerical calculations of t he internal force of pile group under different magnitude and obliquity loads is made by the program 此外，采用本文程序对不同荷载量级及倾角下群桩基础的内力进行了大量的数值计算。
In addition , the friction piled foundation , creep pile foundation , the piled raft foundation and the padded pile foundation are the main models to be analyzed 主要分析了沉降控制复合桩基、减少沉降桩基础、疏桩基础、带褥层群桩基础等。
So each pile does n ' t enter the limit state simultaneously and therefore it is necessary to study the reliability of the group piles 事实上，桩基础中各桩的桩顶反力并不相同，因而各桩并非同时进入极限状态。因此有必要对群桩的可靠性进行研究。
Combining these formulas with some earthquake intensity and site - eigenperiod , the lateral seismic responses of free - head and fixed - head pile groups were calculated 结合具体的抗震设防烈度和场地特征周期，计算了成层地基中群桩的横向地震响应。
