求翻译：按照规范规定，桩顶分级施加垂直荷载，可测得各级荷载作用下的沉降量。即可得到Q-S曲线。如果曲线有明显拐点可以简单的确定单桩竖向承载力，而对于Q-S曲线呈缓变型的桩基，要对其承载力进行预测。常用的预测方法有(1)双曲线预测法；(2)灰色预测模型；(3)最小二乘法等。是什么意思？

According to specification, grading pile vertical load applied can be measured under load at all levels of the settlement. QS curve can be obtained. If the curve is a clear inflection point can easily determine the vertical bearing capacity of single pile, and was slow for the QS curve variant of th

In accordance with provisions regulating relations between piles, vertical load, hierarchical imposed loads role at all levels can be measured in the deposition. You can get it from - S Q curve. If there is a clear inflection point can be a simple curve determine a pile of vertical endurance Q - S c

Stipulated according to the standard that, the head of pile graduation infliction vertical load, is observable under all levels of load function subsidence quantity.Then obtains the Q-S curve.If the curve has the obvious inflection point to be possible the simple indeed order form pile vertical supp

According to the requirements specification, pile top grade imposed vertical loads, with measurable levels load under the settlement. To get your q-s curve. If the curve there is a clear turning point can be simple determination of vertical bearing capacity of single pile, and for sustained variant
