摘要
通过现场足尺试验、数值模拟,研究了PHC单桩、复合地基承载及变形特性。分析表明:复合地基是通过一定沉降量来达到桩土共同作用目的,其沉降比单桩大;随荷载增大,土体分担荷载比逐渐减小,在减小至35%时趋于稳定。
A full-scale field test and numerical analysis were conducted to learn the hearing and deformation characteristics of PHC single pile and composite foundation. Composite foundation needs a certain settlement, which was greater than that of single pile, to achieve the purpose of working together of both pile and soil With the increasing of load, the load-sharing proportion of soil decreases gradually until to 35%.
