摘　　要：介绍了根据孔隙挤密原理推导的建筑纠偏生石灰桩使用量的计算理论,详细地阐述了模型试验的方法和步骤,并将模型试验结果与计算理论的计算结果进行了比较,验证了该理论的正确性,使其更加合理与完善,为湿陷性黄土地基上采用膨胀法纠偏加固危房提供了理论依据.Slauting buildings can always be found in collapsible loess regions because of the improper ground treatment. The ununiform sedimest of the foundations and the inclination of the upper-structures will bring about great dangers. First the calculation of the amount of expanding materials is made, based on interspaces which need to be compressed so as to rectify and reinforce the slanting buildings by using expansive method. Then the method and details of the model test are described . Finally the discrepancies between the results of model test and the theoretical calculations are discussed. But they are basically matched with each oterh, so the theory is proved to be true. It lays a theoretical foundation for slanting buildings on collapsible loess and can be used for references for engineers.
