| 摘 要： | 通过改变设计参数,对混凝土桩与石灰桩多元复合地基进行一系列室内模型试验,得到混凝土桩与石灰桩多元复合地基的荷载沉降曲线特征.混凝土桩、石灰桩和桩问土的应力特点,桩土应力比特点.该模型虽然不能完全模拟现场混凝土桩与石灰桩多元复合地基的工作性状,但从定性上分析混凝土桩与石灰桩多元复合地基的工作性状是可行的.试验表明,对于粉细砂类土,混凝土桩与石灰桩联合处理的效果很好.

| Abstract: | A set of apparatus of foundation physical model has been developed and utilized to conduct model tests of multielement composite foundation on concrete column and lime column.By changing design parameters(strength of concrete column and replacement ratio of lime column),a number of features of multielement composite foundation on concrete column and lime column have been obtained,including the characteristics of load-settlement curves,stress of the columns,stress between columns,column-soil stress ratio,and... |
