安庆成品油管道穿越河道工程渗流稳定分析
摘要:在安庆成品油管道穿越河管道工程的施工过程中,管道的穿越会对河道、堤防的渗流产生影响。利用有限差分法对穿越后的堤防进行了渗流稳定分析与计算,建立了地下水流数值模拟模型。通过对地下水流数值模拟结果的分析,并利用临界水力梯度法,对实例中定向钻穿越河道工程诱发渗透破坏的可能性,进行了定量分析。
Abstract:In the construction process of Anqing product pipeline crossing river course project,pipeline crossing will affect the seepage of river channel and embankment.In this paper,the finite difference method is used to analyze and calculate the seepage stability of the embankment after the pipeline crossing,and groundwater flow numerical simulation model is established.Based on the analysis of numerical simulation results of groundwater flow and the application of critical hydraulic gradient method,the possibility of seepage failure by directional drilling crossing river course is analyzed quantitatively.
