摘要
由于地基软弱土层分布不均匀等原因,某6层综合楼严重倾斜,倾斜率高达20‰,并呈恶化趋势。为此,采用水平掏土纠偏法与注浆加固相结合的综合治理方案对该建筑物进行了纠偏,取得了良好的效果。通过该工程实践,阐述了基底水平掏土纠偏法信息化施工的全过程,并指出在使用得当的情况下,在淤泥质粉土地基中进行注浆是可以取得良好加固效果的。本次纠偏加固方法的成功实施,对类似工程具有一定的借鉴作用。
A six-story building tilted seriously because of subgrade soils' non-uniform distribution.Its gradient of slope is up to 20‰,and the inclination is developing now.To rectify the deviation,a synthetic scheme by horizontal digging and grouting was made and carried out.After completion,the average inclination decreased to 5.8‰.A satisfactory result was gained.By this project,not only the importance of information construction but also the applicability of grouting in silt subgrade was set forth.
