水闸地基不均匀沉降的有限元分析

Analysis of Finite Element on Uneven Settlement of Sluice Foundation

水闸地基不均匀沉降对水利设施的安全稳定运行造成严重影响,因此对地基的不均匀沉降进行监控,并设置符合当地实情的监控指标尤为关键。借助有限元软件进行建模,考虑各工况对实际水闸地基不均匀沉降的影响,拟定对水闸地基不均匀沉降的安全监控指标。通过与实际沉降量对比可知,该方法拟定的监测指标具有节省人力成本、评判结果与实测结果相关性高等优点。

The uneven settlement of the sluice foundation poses an important challenge to the safe and stable operation of water conservancy facilities,so it is particularly important to monitor the uneven settlement of the foundation and set monitoring indicators in line with local conditions.With the help of finite element software for modeling,considering the influence of each working condition on the uneven settlement of the actual sluice foundation,the safety monitoring index for the uneven settlement of the sluice foundation was formulated,and by comparing with the actual sedimentation,it was found that the monitoring index proposed by this method had the advantages of saving labor cost and high correlation between the evaluation results and the measured results.
