碩士 === 逢甲大學 === 土木及水利工程所 === 90 === We have got the monitoring datas of Nanhau earth dam. According to these monitoring datas. We got the distributions of the total head pressure and pore pressure. This study we used software package Seep2D model of the GMS to simulate stable type seepage. We compared and explored each other crossly by the results of simulations and monitoring datas. In order to understand the differences by this two datas. The results of the simulations and monitoring datas are almost the same at up and down stream. But the errors reach to 13% at the central parts of the earth dam, the reason is the central part of the earth dam was over compacted.（during the construction of dam） Totally speaking, we proof this model can be used to simulate the dam’s seepage. This is a great assistance for the dam’s safe-assessment by simulation of the whole dam’s distributions of the pore pressure and total head pressure.
