Abstract

Abstract: Throughout geotechnical laboratory test and in-situ water immersion plate load tests, this paper presents the comparative results of two different methods in the deep treatment of collapsible loess soils: compacted lime-soil and cement soil columns. The scope of applying the compacted column in the collapsible loess is to eliminate the potential collapsibility of foundation soils when they are wetted. The results of the plate loading tests on the composited ground was used to select the effective ground improvement method for the proposed cooling tower foundation of a power plant.

Key words: lime-soil compaction columns, compacted cement-soil, laboratory tests, water immersion plate load tests, collapsible loess
