基础抗浮与大体积混凝土施工技术措施的结合运用

文章以华中某特大项目的地下室工程为背景,结合地下室实践生产中遇到的技术难题展开探索,通过综合分析地下水和大体积混凝土对地下室结构施工的不利影响因素,并从降低混凝土水化热和泄水减压两个角度展开探索,试图将基础抗浮与大体积混凝土施工工艺进行结合运用,以寻求能够同时解决地下室底板上浮和大体积混凝土有害裂缝问题的双重技术措施。

Based on the basement project of a super-large project in central China as the background,as regards the technical problems encountered in the practical production of the basement,this paper comprehensively analyzes the adverse influence factors of groundwater and mass concrete on the construction of basement structure.From the two angles of reducing the hydration heat of concrete and reducing the pressure of water discharge,this paper attempts to combine the anti-floating of foundation with the construction technology of mass concrete,in order to seek the dual technical measures which can help solve the problems of basement floor floating and mass concrete harmful cracks at the same time.
