摘　　要：超长超厚混凝土结构在施工和使用中易产生裂缝,控制裂缝的产生是超长超厚混凝土结构施工的关键。文中结合中国石油大厦地下结构工程实际情况,讨论了超长超厚混凝土结构的材料选用、设计、施工注意事项、养护方法等抗渗防裂措施,目的在于为其它超长超厚混凝土结构的施工提供参考。The ultra-long and ultra-thick concrete structures usually induce several cracks during its con- struetion or sevice life. One of the key problems during design and construction of ultra-long and ultra-thick concrete structures is to prevent the cracks. According to the actual situation in underground structures of Chi- na Rock Oil Mansion, the paper has discussed the constructional technic of ultra-long and ultra-thick concrete structures such as material select, design, matters needing attention to construction and concrete euring meth- ods for preventing from cracking and seepage. And the study provides a reference for the construction of ultra- long and ultra-thick concrete structures.
