摘要
轿子山水库坝址地层为侏罗系禄丰组砂泥岩互层,地质构造及物理地质现象发育,坝址区内砂岩、裂隙发育的粉砂质泥岩为含水(透)水层,较完整砂岩、粉砂质泥岩为相对隔水层,因陡倾角节理发育岩体透水性差异变化较大。为工程安全起见,分析并研究坝址区附近工程地质条件,对于建坝防渗具有重要意义。
Formation of Jiaozi mountain reservoir dam site is sand-shale interbeded formation in Jurassic system of Lufeng formation. Geological structure and physical geological phenomenon develops. Sandstone in the dam site area and fractured silty mudstone are aquifers（permeable layers）. Complete sandstone and silty mudstone are relatively aquifuges.The paper analyses geological conditions near the dam site engineering research for the engineering safety. It has important significance for dam seepage.
