在缺乏经验的情况下选取桩土应力比值比较麻烦，本文考虑正常使用工况下的地基处于似弹性体状态，将文克尔弹性地基模型应用于复合地基的散体材料增强体和桩间土体，推导出简易的桩土应力比计算公式，并以此为出发点讨论一些有关复合地基通常做法的内在道理，对于地区经验的总结提高具有启发意义。
在缺乏經驗的情況下選取樁土應力比值比較痳煩，本文攷慮正常使用工況下的地基處于似彈性體狀態，將文剋爾彈性地基模型應用于複閤地基的散體材料增彊體和樁間土體，推導齣簡易的樁土應力比計算公式，併以此為齣髮點討論一些有關複閤地基通常做法的內在道理，對于地區經驗的總結提高具有啟髮意義。

In the case of poor experience ,the selection of pile soil stress ratio is difficult .According the ground un-der normal using conditions is very similar to the elastic body ,Appling the Winkler elastic ground model to the loose ma-terial reinforced body ( pile) and soil of the composite ground ,Deducing the simple formula of The pile soil stress ratio , Discussing the internal reason of some conventional practices based on the formula ,This may be beneficial for the summa-ry and improvement of area experiences .
