Abstract

Effects of sand compaction piles on ground improvement of a coal ash pond and axial performance on four drilled shafts through improved coal ash layer at a power plant in southern Taiwan is studied in this paper. Effects of the sand compaction piles improvement is evaluated by comparing the SPT-N values before and after ground improvement. The load versus displacement relation at head, the axial force along the shaft, the t-z curves and/or the toe q-z curve, which are the main concerns of shaft load test results, are presented and discussed in the paper.

Use of Sand Compaction Piles for Improvement of a Coal Ash Pond

Arlington, Virginia
