摘要
金茂大厦混凝土工程施工技术在两方面创了新高：其一是超深（－１９．６ｍ）的厚４ｍ的大体积混凝土基础承台，混凝土强度等级创新高达Ｃ５０；其二是超高层泵送商品混凝土一次泵送高度创新高达３８２．５ｍ。本文主要介绍该工程混凝土施工中所采取的一系列技术组织措施。
The construction technology for concrete structure of Jinmao high rise building set new records in two aspects,one of which is the new record of concrete strength(C50) set in the construction of super deep(-19 6m) mass concrete foundation capping beams;another of which is the new record of the pumping head(amounting to 382 5m) of the ready mixed concrete pumped to the top of super high rise building.This article describes mainly the series of technical organizational measures taken in the construction of the project.
