单桩承载力荷载度公式法

Load Ratio Formula Method of the Bearing Capacity of Single Pile

荷载度公式法是通过桩重(力)与桩(头)位移求取桩极限承载力的一种方法。该公式是由一系列成功的动静对比的结果厘定的实验公式。该文对公式的理论问题、应用范围、位移标定、精度分析、质量损耗等方面进行了初步研究。并对公式法的应用前景进行了探讨。

Load ratio formula method is a new method of deducting the ultimate bearing capacity of pile by ratio between pile gravity and pile displacement. It is an experimental formula derived from the results of a series of successful dynamic and static testing comparison. This paper preliminarily studies such aspects as the theoretical problems, applicable scope, displacement calibrating, accuracy analysing, mass loss of the formula, and it also probes into the further application of this method.
