Summary:The utility model discloses a dam foundation stratum lifts deformation control structure. Dam foundation stratum lifts deformation control structure is including setting up the checkdam on the dam foundation, dam foundation below is from last to divideing into the stratum of permeating water, relative impermeable stratum and permeable stratum down in proper order, be equipped with the pressure release corridor in the checkdam to and a plurality of pressure release holes of setting in the dam foundation, the top and the pressure release corridor intercommunication in pressure release hole, the bottom in this pressure release hole is located the permeable stratum. The utility model discloses the deep drainage pressure release that the stratum penetrability distributes, the control stratum produces seepage deformation has been changed to realize to reduce and eliminated the stratum that the reservoir retaining arouses and lift the deformation.
