摘　　要：以简易试验沙槽模拟为研究手段,GMS软件模拟为辅助验证,研究排泄条件、介质结构、局部热源对地下水流系统的影响。试验发现:排泄点的增加导致地下水流系统由简单向复杂转变;弱透水或隔水介质的加入,使地下水流形态发生巨变,循环可由潜循环向深循环转变;热源仅在其附近一定范围内引起流线偏移,温度的升高导致流体渗流速度加快。Based on simple experiment sand tank and GMS,we studied three factors which impact froundwater flow system,includinf discharfe, medium field and heat source. The results show that increasinf discharfe points lead a complex froundwater flow system. With Joininf of aquitard or aquiclude,froundwater flow patterns chanfe dramatically and water circulation chanfes from shallow to deep. However,flow lines deflect in a certain scope of heat source. Indeed,because of increasinf temperature,seepafe velocity accelerates in a certain ranfe.
