摘要
以西藏满拉水利枢纽为案例,从渗流分析的基本理论和计算方法着手,对西藏地区覆盖层较厚的土石坝进行渗流分析。通过渗流方程和热传递能量方程的相似性,利用Ansys的热处理模块对大坝的渗流进行数值模拟和计算,通过计算的结果和现场测压管的水头观测值进行对比和分析,结果表明,Ansys可应用于工程设计中的渗流计算,从而对土石坝后期加固处理具有指导性。
With the case of Laman Project in Tibet,seepage of the earth- rock fill dam on the thicker overburden in Tibet Autonomous Region is analyzed based on the basic theory and calculation methods for the seepage analysis. Through the similarity of seepage equation and thermal transmission energy equation and by application of the Ansys thermal handling module,the seepage value simulation and calculation are carried out. Comparison and analysis of the calculation results and the measured water head by piezometer prove that Ansys can be utilized for the seepage calculation. Accordingly,it can guide the late reinforcement of the earth- rock fill dam.
