Soil Investigation of Fly Ash Deposit Improved by Heavy Compaction Method
Publication: Journal of Geotechnical and Geoenvironmental Engineering
Volume 138, Issue 6
Abstract
An in situ test program was undertaken to systematically investigate the effectiveness of the heavy compaction method (HCM) normally used for sandy soils for compacting fly ash deposit. Measurements of soil performance and cone penetration tests before and after the compaction were carried out, indicating obvious effects on soil properties and strength increase in the improved ground. It has been found that HCM introduces three-dimensional (3D) nonuniformity in the upper part versus horizontally uniform layers in the lower part of the improved ground. Also found is that the HCM-induced vertical soil strain is almost proportional to the ratio of cone resistance increment to the prior-treatment cone resistance in the uniform zones.
