摘要
新建海河大桥位于现海河大桥东侧,主桥为双索独塔斜拉桥结构,主塔承台尺寸为46.5 m×34.5 m×5 m,混凝土方量约8 021.3 m3,属大体积混凝土施工。简要介绍了其主塔承台基坑支护、大体积混凝土温度控制等施工关键技术。
The newly-built Haihe Bridge lies at the east of the existing Haihe Bridge. The main bridge is double cable, single tower cable-stayed bridge structure. The size of main tower cap is 46.5 m×34.5m× 5 m with the concrete of about 8 021.3 m3. It is a large cubage concrete construction. The article briefly explains the key construction technology for main tower cap foundation pit support and large cubage concrete temperature control, etc.
