1 大坝碾压试验1.1 试验材料试验时垫层料生产系统尚未形成,采用掺和法生产的符合设计级配要求灰岩垫层料;过渡料、灰岩主堆石料及灰岩次堆石料前期取自花尖脑料场爆破试验合格料,后期取自溢洪道开挖爆破灰岩料;页岩次堆石料取自上游料场的导流洞洞挖料;砂卵石则采用坝基河床开挖料,各种料填筑前均经筛分试验级配合格后使用。固坡混凝土由江南公司拌和站拌制后运至试验现场人工人仓。1.2 试验场地及规模
1 Dam Rolling Test 1.1 Test Materials When the cushioning material production system has not been formed during the test, the limestone cushioning material, which meets the design grade requirements, produced by the blending method; the transition material, the limestone main rockfill material and the limestone secondary rockfill material The early stage was taken from the Hupengnao material field blasting test qualified material, the latter was taken from the spillway excavation blasting limestone material; shale sub-rockfill material from the upstream material yard diverting hole excavation material; sand and gravel is the use of dam foundation bed excavation Materials, all kinds of materials before filling the screening test level with the grid before use. Solid concrete slope by the southern mixing plant mixing station shipped to the test site artificial manhole. 1.2 test site and size
