An Improvement of the Method of Determination of Beraing Capacity for Piles by High Strain Dynamic Test
-
摘要: 从高应变动测的特点出发，提出了一种分析桩基承载力的拟合模型。该模型在分析桩单元中的上行波和下行波时，既考虑单元周边土阻力的影响，又考虑单元惯性力和单元沉降的影响，使计算结果更接近实际情况。为验证模型的正确性，最后给出了一个工程实例Abstract: As a new method of determination of bearing capacity of pile, high strain dynamic test technology has been used widely in our country and abroad. In this paper, an improvement is given in which the inertial force of pile is taken into count in calculation of shaft resistance of soil by using pile-soil element analysis based on one-dimensional stress wave propagation theory . To prove its reliability, a field high strain dynamic test in presented and the beraing capacity of pile is calculated with the data from the test by using the method presented in the paper.
