求翻译：减压井导渗原理是：通过滤水管将来自上游渗透水流直接导入井内，阻止水流往下游流动，在地下迅速降低压力水头，以达到保护大坝的稳定和降低下游地下水位的目的。本工程在大坝下游设置排渗减压井。是什么意思？

Relief well lead seepage principle is: through the filter penetration of water from upstream water directly into the wells to prevent water flow downstream, to quickly lower the pressure head in the ground, to protect the dam's stability and reduce downstream water table purposes. The project set up

pressure reducer Tseng ABM seepage principle is: by filtering water mains will be derived from the upper reaches directly import penetration in the well water and to prevent water flow to the lower ground floor, rapid decrease in hydraulic head pressure, so as to protect the stability and lower dam

Reduces kills the well leads infiltrates the principle is: Will come from upstream through the strainer will seep the current of water to induct in directly the well, the impediment current of water will be mobile toward the downstream, in underground will depressurize the flood peak rapidly, achiev

Relief wells in permeable principle is: by filtering water from the upper reaches of seepage flow directly into the well, block water flow to the downstream flow of underground quickly lower pressure head to achieve the purpose of protecting the dam stability and reducing downstream groundwater.
