本文叙述了3吨重锤夯实处理填土地基作浅基础的工程实例,通过试验、设计及施工的实践,着重讨论了夯击方法的优劣;针对粘性土的特性,探索夯击时强度的变化;还对建筑物进行了较详细的沉降观测,从中发现经过一定重量级的锤夯击后的土体,往往出现超压密状态,因而引起建筑物在一定荷载及时间内发生“上抬”现象,对此作了一般性阐述。此外,就这种处理方法提出了今后需要研究的几点建议意见。
This article describes an example of a 3 ton heavy hammer compaction treatment for filling the ground as a shallow foundation project. Through trials, design and construction practices, the advantages and disadvantages of the slamming method are discussed. The strength of slamming is explored for the characteristics of the clay. Change; also conducted a more detailed settlement observation of the building, found that after a certain heavyweight hammer slamming the soil, often over-compact state, causing the building to occur in a certain load and time “uplift ”The phenomenon is described in general terms. In addition, some suggestions for future research are proposed on this approach.
