The invention discloses a stone-building concrete dam construction method. The method comprises the steps of site pretreatment, layer formwork installation, seepage drainage mechanism arrangement, rock-fill warehousing, concrete pouring, rock-fill concrete curing and repeating till construction is completed. When each layer of the dam body is poured, the seepage draining mechanism for draining seepage is arranged at the bottom of the rockfill material in advance, and then the rockfill material is stacked and the concrete is poured, so that each layer of the dam body is provided with the seepage draining mechanism capable of draining seepage; the seepage drainage mechanism is composed of a seepage drainage pipeline and a water drainage pipeline, seepage water in the dam body is collected through the seepage drainage pipeline and delivered into the water drainage pipeline, and therefore the seepage water in the dam body is rapidly and effectively drained, and the influence of the seepage water on the dam body i
