尼尔基主坝碾压式沥青混凝土心墙施工质量控制

尼尔基水利枢纽工程主坝为碾压式沥青混凝土心墙砂砾石坝（导流明渠段采用浇筑式沥青混凝土心墙），此种坝型在我国北方寒冷地区是首次采用。通过对原材料、沥青混凝土制备和现场铺筑的质量控制，经采用无损检测和钻孔取芯样对成墙质量的检验，工程优良率达到100％，并创造了多项国内施工记录，为国内沥青混凝土心墙施工积累了宝贵经验。

Workmanship control of the rolled asphalt concrete of the central core in the Ni'erji main dam

The main dam of Ni'erji water conservancy project concrete is the rolled asphalt concrete central core gritstone dam(the open diversion channel is poured asphalt concrete central core).This is the first time to use this style dam in the north cold district in China.Through the control of the preparation of raw materials and asphalt concrete and the quality of the local poured,the test of the quality of the central core by the non-destructive test and coring,the ratio of the project choiceness is up to 100%,it created multiterm internal construction journal and it accumulated invaluable experience for the construction of the asphalt concrete central core.
