以某大桥主墩混凝土工程为例，针对大体积混凝土水化热大、易出现裂缝等特点，从承台分层浇筑、原材料控制、配合比设计、温度监控等方面，阐述了大体积混凝土的施工关键点，有效确保了混凝土施工质量。%Taking the concrete project of the main pier of some bridge as the example,the paper illustrates the construction key points for the large concrete from the layer grouting of the cushion cap,control over raw materials,design of proportional ratio,and temperature monitoring ac-cording to the features of the big hydration heat and cracks of the large concrete,so as to ensure the construction quality of the concrete.
