摘要
为了更好地解决基桩缺陷量化分析问题,从建立成层土中缺陷桩桩土系统模型入手,引入矩阵递推法,求解出成层土中多缺陷桩桩顶和桩身任意点的瞬态响应解析解,并应用此解对缺陷桩瞬态响应影响参数进行分析,得出在利用幅值比进行缺陷量化分析方法中的关键影响因素为桩侧土阻尼系数,为成层土中基桩缺陷量化分析和承载力评价奠定了理论基础。
For the problem of pile defects quantization analysis well resolved, the instantaneous response solutions of multi-defects pile on top and arbitrary location were obtained by matrix recurrence method based on the model of defective pile-soil system in stratified soil. Then some parameters affecting the response were researched here too. The result is that the coefficient of pile around soils is a key factor to the solution, which provides theory foundation for defects quantization analysis and load bear of piles in stratified soil.
