摘　　要：含水层水流在重力势 -介质压缩作用下 ,水头随介质压密而增高 ,渗流速度随介质压密而减小。含水层水流在重力势 -温度差 -介质压缩作用下 ,当温度不足以改变流体的物理性质时 ,水头与温度分布有关 ,线性温度分布对水头无影响 ,而非线性温度分布使水头随温度升高而增高 ;当温度足以改变流体的物理性质时 ,水头随温度升高而增高。When the mechanisms of gravity and compaction driven flow in confined aquifer are taken into account, hydraulic head increases and seepage velocity decreases with compaction in a confined aquifer. When the mechanisms of gravity , temperature and compaction driven flow in a confined aquifer are considered and temperature is not enough to change physical properties of the flow, hydraulic head is associated with the distribution of temperature in a confined aquifer and is not influenced by the linear distribution of temperature. If the distribution of temperature is nonlinear, hydraulic head increases with temperature increase. When temperature is enough to change physical properties of the flow, hydraulic head increases with temperature increase. The seepage velocity increases with the increase of temperature gradient.
