• The affect of top ring beam has not been thought highly at presenti which has been regarded as the safety measure . the whole retaining and protecting structure of piles in row and top ring beam is calculated by the method of cantilever beam , and the result is not reasonable obviously
  在当前的设计与施工中，桩顶圈梁的作用未引起足够的重视，普遍将其视为安全储备，而将排桩与圈梁的整体支护结构视为悬臂梁来计算的，这样的计算结果显然过于保守不尽合理。
• The top beam can reform the force - bearing mechanism of the retaining piles because the cantilever piles can be fixed by adding a restriction on the top of the piles and the displacement of the piles can be reduced too . as the same time , top beam can harmonize the displacement and force of the piles and avoid the phenomenon of chain failure as one of the piles is destroyed . if the top beam are closed it can work well because the support on the two ends
  桩顶圈梁对支护桩的作用主要体现在：改善支护桩的力学性状，变悬臂桩为顶端约束的超静定状态；对桩顶位移起限制作用，减小基坑工程对周边环境的不良影响；协调各桩之间的受力和位移，避免局部受力过大引起各桩之间的连锁破坏现象。
• Study on the mechanism of the top beam that used in retaining and protecting piles of deep foundations is the uppermost section of this master degree thesis . the classical structure mechanics method and the finite elements analysis software are used to calculate and analyse the internal force of the piles - top beam retaining system . based on the research of the mechanism of the top beam , the optimal design of piles in row is discussed
  本文针对深基坑排桩支护桩顶圈梁设计计算中存在的问题，以桩项圈梁的作用机理为主要研究内容，分别采用传统的结构力学矩阵计算方法和有限元分析软件对排桩?项圈梁支护体系内力进行计算和分析，对桩项圈梁作用的力学机理进行了深入的研究。
