阎王鼻子水库设计为全断面碾压混凝土重力坝，施工中由于受工程规模、结构、设备等因素的影响，碾压混凝土施工工艺不但不能发挥经济快速的优势，而且不利于质量控制．为适应本工程的施工条件和设计条件，将具有抗冻要求的外部混凝土改为常态混凝土，同时研究了内部为满足绝热温升等指标要求的高粉煤灰掺量的常态混凝土，不仅加快了进度，而且提高了质量．
Yan Wang nose reservoir design for the whole section of RCC gravity dam, construction due to the project size, structure, equipment and other factors, RCC construction process not only can not play a fast economic advantages, but also not conducive to quality control. In order to meet the construction conditions and design conditions of this project, the external concrete with anti-freezing requirements was changed to normal concrete. Meanwhile, the normal concrete with high content of fly ash to meet the requirements of adiabatic temperature rise and other indicators was studied. Progress, but also improve the quality.
