实践表明，浇筑式沥青混凝土适用于寒冷地区土石坝的防渗心墙。
The practice indicates that the asphalt concrete ADAPTS to the core wall of earth-rock dam in the cold region.
拦河主坝坝壳以当地材料砂砾石为主，防渗心墙比较了粘土心墙、沥青混凝土心墙和斜墙型式。
The material of the main dam shuck is mainly the local sandy gravel. The clay core and the asphalt concrete core were compared in the choosing of seepage prevention type.
黄壁庄水库副坝防渗心墙加固工程所需高性能混凝土，要求和易性好、早期强度低、后期强度高、抗渗性能好、低弹模和高抗拉强度。
The high performance concrete for core wall of earth dam must be good workability, low early strength, high final strength, high seepage resistance, low elasticity modulus and high tensile strength.
