The primary factors , which affect the utmost capacity and ascending displacement , are construed by using the fem . and some suggestions about how to design tension piles are made 利用有限元对影响抗拔桩q ? s曲线的主要因素进行了分析，且对抗拔桩设计提出了几点建议。
Failure modes of the tension piles are introduced first . based on the failure modes , the utmost bearing capacity calculations of single uniform - section pile are analysed and studied 首先介绍了抗拔桩的破坏模式，并在此基础上分析研究了的等截面抗拔桩单桩极限承载力计算。
Tension piles are widely used for resisting uplift loads of underground structures such as deep basement and underground transformer substation , and foundations for tall buildings subjected to high bending moments 摘要抗拔桩常被应用于地下构筑物的抗浮和受较大弯矩作用高耸构筑物的基础。
Abstract : an engineering case is introduced to illustrate the design ， construction and test of extruded - expanded bored pile with support tray . good ability of anti - pull for this type of pile is indicated 文摘:通过工程实例介绍了挤扩支盘灌注桩的设计、施工与检测，指出该种桩具有良好的抗拔性能。
The stress and deformation mechanism of expanding - bottom tension piles is analysed . then primary factors , which affect the utmost capacity and ascending displacement , are offered and discussed 对扩底抗拔桩的受力和变形机理进行了分析，并在此基础上探讨了影响抗拔桩极限承载力和上拔量的主要因素。
Furthermore , the results of laboratory tests , totally 57 small - scale specimens , are presented that it is a much complex process that load being transferred from inserted angle steel to concrete foundation 3 、本次57个试件的角钢抗拔试验表明，作用力从插入角钢传到混凝土基础是一个非常复杂的过程。
The q - s curves which describe relations of load and displacement are simulated by power - function math models . and the method to forecast utmost bearing capacity of anchor - hold tension piles is offered 运用幂函数数学模型对抗拔桩q ? s曲线进行模拟，并在此基础上提出了对锚桩抗拔极限承载力预估的方法。
According to the static - load tests data , the differences of side frictions about the tension piles and the pression piles are contrastively analysed . the ratio between tension piles " side friction and pression piles " side friction is closed to 0 . 8 利用桩的静载实测资料，对浙江软土地区抗拔桩和承压桩侧摩阻力的差异做了对比分析，并得出它们的比值为0 . 8左右。
