摘　　要：介绍了根据孔隙挤密原理推导的生石灰桩使用量的计算理论,详细地阐述了采用模型试验实现该理论的方法,将模型试验结果与理论计算结果进行了比较,验证了该理论的正确性,使得该理论更加合理与完善,从而验证了湿陷性黄土地基上采用膨胀顶升法纠偏加固危房的可行性.A principle for calculating the consumption amount of quick lime piles derived from porosity densification principle was introduced and, then, a model test method for implementing this principle was expounded in detail. The result of model test was compared with that of theoretical calculation and the validity of this theory was justified, making it even more reasonable and complete. Thus the feasibility of employing the expansion-rising method to rectify and reinforce endangered buildings on the ground of collapsible loess was verified.
