【摘要】 从整理分析工程实测桩土应力比试验资料入手,阐述了桩土应力比与外部荷载及其桩土应力比与沉降之间的相互关系.研究了不同模量的垫层对桩土应力比及桩、土应力水平发挥的影响规律,对复合地基的优化设计具有一定的参考意义.更多还原

【Abstract】 By arranging and analyzing actual engineering experimental data of stress ratio of pile-soil,the correlation of stress ratio of pile-soil and external load and the relation of that and settlement is expounded. It discusses how the different modular cushion affects on stress ratio of pile-soil,and on the development of the stress level of pile and soil , which has a reference significance to optimum design of composite foundation.更多还原
