摘要
以由盐渍土、石灰、石子组成的材料(三合土)对地基进行回填处理工程为例,通过一系列三合土物理力学性能实验,分析了三合土的抗压强度以及影响因素.对以此种盐渍土改性后的材料作为基础的地基进行了实测和沉降监测实验研究.结果表明,使用三合土换填处理地基是一种实用且经济的地基处理方法.
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.
