干贫混凝土在宜兴抽水蓄能电站的应用

Application of Dry Lean Concrete to the Yixing Pumping-storage Power Plant

干贫混凝土是由砂石骨料掺入少量水泥拌制而成的一种填筑材料。本工程用于北库岸填筑、库岸和库底大型岩脉及囊状风化带处理。干贫混凝土填筑施工速度较快,经过处理后边坡稳定,地基承载力和变形满足设计要求。现主要介绍干贫混凝土的性能及其在宜兴抽水蓄能电站上水库北库岸填筑中的应用情况。

Dry lean concrete is a filling material made of sand aggregate mixed with cement.It is applied to the filling of the north bank of the reservoir and the treatment of the large rock vein at the bank and bed of the reservoir as well as the cystiform efflorescent band.Dry lean concrete,which helps finish filling rapidly,is able to guarantee the stability of the back side slope and satisfy the requirements of loading and deformation of the groundwork.The paper hereby mainly introduces the property of dry lean concrete and its application to the filling project of the north bank of the upper reservoir of the Yixing Pumping-storage Power Plant.
