| Abstract: | With tabia which is composed of saline soil, lime and crushed stone as an example of backfill engineering, a series of experiments of physical and mechanical properties were carried out to investigate the compressive strength and contributing factors of tabia. The settlement of the modified saline soil as foundation material was monitored. The settlement monitoring results show that this tabia replacement method is practical for ground treatment. |
| Keywords: | saline soil foundation treatment replacement method settlement monitoring |
