摘　　要：土基上水闸闸基渗流的安全问题是水闸安全的重要部分,目前主要分析方法包括改进阻力系数法、流网法和有限单元数值方法。相比于前两种手工算法,有限元具有方法先进、适应性强、操作简便等优点。本文基于水工专用软件Autobank的有限元渗流分析模块,在简单闸基渗流分析验证其准确性的基础上,对江苏溧阳某中型水库溢洪闸闸基渗流进行分析。该溢洪闸下游泄槽及消力池底板下设有排水层,且泄槽底板倾斜,采用有限元渗流分析可以避免过多的假定与简化。计算结果显示,采用Autobank对复杂闸基进行渗流分析,结果合理且高效。The seepage safety problem of the sluice foundation on soil foundation is an important part of the safety of the sluice.Currently,the main analysis methods include improved resistance coefficient method,flow network method,and finite element numerical method.Compared to the previous two manual algorithms,finite element method is the latest method,has strong adaptability,and is to operate.This article is based on the seepage analysis module of the hydraulic analysis system Autobank.On the basis of verifying the accuracy of a simple gate foundation seepage analysis,it analyzes the seepage of the spillway gate foundation of a medium-sized reservoir in Liyang,Jiangsu.There is a drainage layer under the bottom plate of the downstream discharge channel and stilling pool of the spillway gate,and the bottom plate of the discharge channel is inclined.Using finite element seepage analysis can avoid excessive assumptions and simplifications.The calculation results show that using Autobank for seepage analysis of the spillway gate is more reasonable and efficient.The practical results of this article indicate that using finite element calculation method to analyze the seepage of sluice foundation has good application value.
