Compared with soil destroyed pattern of vertical force and its controlled factor of bearing capacity,it is concluded that pile capacity and its tip resistence have some difference when soil with the same physical mecanic property is used as natural foundation and pile tip resistent layer.Whereas the middle weathering rod Stratum hasn't this property,that is to say it has the same bearing capacity and pile tip resistence.

文摘：通过竖向荷载下土体的破坏模式及其承载能力控制因素的比较，论述了物理力学性能相同的土层作为浅基础的天然地基与桩端持力层时，承载力值与桩端阻力值应存在一定的差异；而中风化程度的同一岩层作为天然地基与桩端持力层时，不具有这方面的差异性，承载力值与桩端阻力值应该相等。

It is analyzed the pile's curvature of assumption and in situ data. Based on the theory of curved beam, the bent pile is analyzed, and the equations of equilibrium and physics are built. Further, it is given the deflection and moment of the bent pile. Some conclusions are obtained.

通过对发生偏斜试桩的偏斜曲线分别按假设曲线和现场实测进行的对比分析，并把曲桩看作曲梁，根据曲梁理论对偏斜桩体进行了分析，建立了平衡方程和物理方程，分析了曲桩在竖向荷载作用下的变形和弯矩。

The research of pile bearing capacity is always a focal issue of research and engineering personnel, combined several highway bridge pile foundation in-suit test results, the bearing capacity of long pile is systematically studied.

桩基承载力的研究一直是科研人员和工程技术人员关注的问题，论文结合多座公路桥梁桩基现场原位试验成果，对深长桩的承载力性状进行了系统的研究。

Based on the dynamic response of bridge pile foundation when adjacent field subjected impact loading, the mechanism of dynamic response of bridge pile foundation is proposed, and the influence to response of bridge pile foundation when isolation barrier is used is also proposed.

本文即以邻近场地作用冲击荷载时，桥梁桩基的动力响应为研究内容，分析了冲击荷载作用对邻近桥梁桩基影响的作用机理，并探讨了采用隔振措施后对桥梁桩基响应的影响。

At the same time, the finite staff element method is used to analyze the influence of beam rigidity; and the two new methods proposed are used to analyze the influence of connect way between piles and beam; and the conclusion is obtained that the rigidity ratio between beam and piles being 0.48 is appropriate; the continuative increase of the rigidity ratio is not significant; the worst condition is that connecting way between piles and beam is hinged; the best condition is that connecting way between piles and beam is rigid. Whether is single-row pile or are double-row piles, when the front of single-row pile or the front of the front-row pile(in the double-row piles) needed excavation, it is supposed to that ought to be carefulness to excavate, because it is that the engineering cost increased greatly.

同时，用有限杆单元法，对双排桩的连梁刚度和用文中提出的方法以桩梁连接方式进行了试验和理论分析得出如下结论：在满足不相互影响排桩间距的情况下，桩顶连梁与桩的刚度比不小于0.48是合适的，此时再增加连梁刚度无意义；桩梁连接为铰结时双排桩受力变形性质最差，刚结时受力变形性质最好；不论是单排桩还是双排桩，桩前和前排桩桩前土体需要开挖时应慎重，因为这种开挖对支护结构影响很大，造价增加很多；双排桩省钱，而且抵抗变形的能力强，值得在工程中研究和广泛应用
