摘　　要：结合某砖混结构住宅掏土纠偏工程实例,通过ABAQUS有限元模拟1∶9,2∶8,3∶7灰土垫层的掏土过程,分析灰土配比、孔径及孔间净距等因素对建筑物纠偏效果的影响规律。研究结果表明灰土垫层沉降量随着掏土孔的增大以及孔间净距的减小而增加。In this paper,an example of excavation correction for a brick and concrete structure is presented. The excavation process of 1∶ 9,2∶ 8 and 3∶ 7 lime soil cushion is simulated by ABAQUS finite element method. The influence of lime soil ratio,pore size and spacing between holes and other factors on the rectification effect of buildings is analyzed. The results show that the settlement of the lime soil cushion increases with the increase of the hole and the decrease of the net spacing between the holes.
