一、枢纽工程施工概况潘家口水库枢纽工程主要由拦河大坝和坝后式电站组成(见图1)。大坝为低宽缝重力坝,缝宽8米,最大坝高107.5米(基础高程123.0米,坝顶高程230.5米),坝顶长1,039.11米。沿坝轴线方向设横缝将大坝分成56个坝段,除特殊坝段外,一般长18米。拦河大坝混凝土250万米~3,电站混凝土20万米~3,水库枢纽混凝土总量近300万米~3。该工程于1975年10
I. Overview of Pivotal Project Construction The Panjiakou Reservoir Hub Project is mainly composed of a barrage dam and a dam-type power station (see Figure 1). The dam is a low-width-gap gravity dam with a slit width of 8 meters and a maximum dam height of 107.5 meters (basic elevation 123.0 meters and crest elevation 230.5 meters) with a crest length of 1,039.11 meters. Set along the axis of the dam transverse joints dam will be divided into 56 dam, except for special dam, the general length of 18 meters. Dam concrete 2.5 million meters dam 3, power station concrete 200,000 meters ~ 3, the total amount of concrete reservoir reservoir nearly 3 million meters ~ 3. The project in 1975 10
