- 摘要:
- 以由粘土、石灰、炉渣、石子组成的材料（四合土）对地基进行回填处理的工程为例，通过一系列四合土物理力学性能试验，分析影响四合土抗压强度的主要因素。对工程竣工后的沉降监测表明，四合土换填处理地基是一种实用的地基处理方法。
By taking the backfilling of foundation with soil mixture of clay,lime,coal slag and gravel as an example,the main factors affecting the compressive strength of this kind of soil mixture is analyzed through a series of physical and mechanical property test on the soil mixture.It is shown,by settlement monitor after completion of the project,that backfilling foundation pits with this kind of soil mixture is a practical foundation construction method.2000,2(2): 18-22 收稿日期：1999-8-11分类号：TU47参考文献：
