采用浅表层技术对新吹填淤泥进行地基处理时,不同排水板间距对地基处理的效果必然不同。根据排水板间距的不同设置试验区,对试验区真空预压过程中的真空度、沉降、孔压进行监测。卸载时进行了钻孔取样和平板荷载试验,并计算了其固结度。

The effectiveness of foundation treatment with different drainage board spacing would be inevitably various, when reinforcement technology of the superficial surface layer was adopted to treat foundation with newly dredged sludge. The test area was set up according to the different drainage board spacing. The vacuum, settlement and pore pressure were monitored during vacuum preloading for the test area. The method of core boring and slab loading test were carried out, and the degree of consolidation was also calculated at the time of unloading.
