摘要
为评价压密注浆处理回填土地基的稳定性,以某压密注浆处理回填土地基工程为例,使用大型通用有限元计算软件ADINA建立模型,用重启平衡初始应力技术等,对回填土地基加固前后的沉降进行数值模拟,并与实测资料进行对比分析。结果表明,采用ADINA软件对压密注浆处理回填土地基进行沉降计算是可行的,计算结果与实测资料基本吻合。通过ADINA软件确定位移等势线,可以更加直观地观察加固地基土的位移、应力等情况,据此可以分析地基处理的稳定情况。
In order to evaluate the stability of backfill foundation treatment with compaction grouting,the settlement conditions of the backfill foundation before and after treating are modelled by using the software ADINA to set up the model and using the restarting technology to balance the initial stress and so on,and they are analyzed and compared with the measured data.The results show that the method as mentioned above is feasible in the calculation of settlement of the backfill foundation treatment by compaction grouting as it could be used to observe the foundation＇s settlement,stress,and so on more directly.
