灰土垫层掏土纠偏试验分析

Analysis on the Experiment of Excavation Deviation of Lime-soil Cushion

通过对不同配比灰土试件进行掏土试验.在掏土孔到地基上表面距离不变的前提下,利用控制变量法、总结归纳法,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,并得出在灰土垫层进行掏土纠偏的工程中采用掏土纠偏技术的关键参数,以指导工程应用.

In this paper,the soil test of different proportions of lime soil was carried out.Under the premise of constant distance from the hole to the ground surface,using the controlling variable method and the summing up method,the effect of lime-soil ratio,pore size and spacing between holes on the rectification effect of buildings is analyzed.The key parameters of the excavation correction technology are adopted in the excavation of the lime-soil cushion,so as to guide the engineering application.
