基于 Autobank 软件的温州海塘工程堤防渗流稳定性计算

摘要

It is well known that seepage is the main reason of embankment failures.After a theoretical analysis on seep-age stability of embankment in Wenzhou seawall engineering project, numerical calculations are also carried out with the Autobank software.Using the auto-mesh function and iteration calculation, locations of the phreatic line and the down-stream exit point in the embankment, as well as the seepage gradient and flow amount are obtained.Then, safety of the embankment is evaluated based on the calculation results.%渗流是引起堤防破坏的主要原因。在对渗流稳定进行理论分析的基础上，利用 AutoBank有限元技术，对温州海塘工程堤防渗流稳定进行计算分析。运用软件的全自动网络划分功能，通过迭代法计算得出堤身的浸润线和下游逸出点位置，并由此计算出渗透坡降及渗流量，最终根据计算结果对堤防在渗流作用下的安全性做出评估。
