摘　　要：北拒马河砂石料具有潜在危害性的碱—硅酸活性,采取抑制措施后用于惠南庄泵站混凝土工程,能够保证结构耐采久性要求。前池及主副厂房采用超长混凝土结构设计与无缝连续施工技术,结合混凝土温控措施,能够保证结构安全。以上技术的采用对缩短工期、降低工程造价、保证结构耐久性和安全性具有重要意义。Because of the alkali reactivity with cement, there is potential harm for the sand and aggregate taken from northern branch of Jumahe River. Measures to inhibit of alkali reactivity must be taken for the sake of structure durability. The long distance concrete structure and continuous construction technology without cracks are adopted in the fore tank and buildings. The structure safety can be ensured by considering the temperature control measures. These measures play big roles to shorter the construction period and cut off the cost as while as guarantee the structure＇s durability and safety.
