Moreover, the tip resistance of pile groups is better used than the single pile.

并且，板下单桩及群桩的桩端阻力均能较充分的发挥出来。

After pressure grouting on pile tip, elastic working range of piles will be extended and be in favour of pile to bear repeated loads and dynamic loads.

桩端压力灌浆后，桩的弹性工作范围延长，有利于桩承受重复荷载和动力荷载。

Failure surface shape of pile tip and ultimate tip resistance was obtained according to Mohr-Column failure criteria.

根据莫尔-库仑破坏准则得出了桩端的破坏面形状以及极限端阻力。

It mattered because of all the hard work and money I invested in my studies thinking a good job awaited me. (Instead I found a pile of dirty dishes and a small tip.) But it was better than being on the unemployment line collecting benefits.
