CASE法的实质及承载力低估的原因探析

An analysis on the nature of CASE method and on the cause of underestimated pile load capacity by this method

ＣＡＳＥ法自称是波动方程的闭合解，但由该法确定的单桩极限承载力要比静载试验结果偏低很多。本文依据波动理论，对该方法的假设是否合理，公式能否成立，承载力低估的原因，以及该方法如何加以改进等问题，进行了探析。

CASE method was claimed by its inventor as a closed form solution of the wave equation.However,the ultimate bearing capacity of single piles predicted by CASE method was much lower than that determined by static load test.The rationality of the assumption of CASE method ,the possibility of the establishment of its formulas,the causes of underestimating the bearing capacity, as well as the way to improve the method are analysed and suggested according to the wave theory in this paper.
