补给作用 meaning in English

alimentation

The results show that ( 1 ) the unconsolidated confined aquifer plays a crucial role in load transfer because of its fluidity and replenishment in time , making the loads of overburden soil evenly transfer into the bedrock through the unconsolidated confined aquifer and the load keep constant during the excavation process ; ( 2 ) under the condition without unconsolidated confined aquifer , the load on the bedrock will be reduced sharply during the excavation
研究结果表明：松散承压含水层条件下，由于承压水的流动性和补给作用，上覆表土层的载荷通过松散承压含水层均匀地作用于下部基岩上，开挖过程中基岩顶界面上的载荷基本保持恒定，松散承压含水层起到均匀传递载荷的作用；无松散承压含水层时，作用在基岩顶界面上的表土层载荷随煤层开挖而显著降低。
