【摘要】 介绍了刚性桩复合地基的研究现状,说明了该种复合地基的承载机理,给出了不同垫层厚度、垫层模量、不同桩长、桩间距、桩间土模量及桩端土模量对桩土应力比和沉降影响的变化规律,并指出了一些参数的取值问题及其它有待进一步研究的问题.更多还原

【Abstract】 Some research circumstances about rigid pile composite-foundation are introduced, and the bearing mechanism of the composite-foundation is pointed out.The varying regularity of the stress ratio and the settlement under all sorts of influence factors are studied.The influence factors include the cushion thickness,cushion modulus,pile length,pile spacing,and modulus of soil between piles.The problem which design parameters should be selected within rational range and problems which need further research are presented.更多还原
