摘要
结合中铁十八局集团石武客运专线驻马店特大桥跨驿阳高速连续梁主墩承台施工,探讨了在中高温天气下及复杂地质环境条件下,采用优化混凝土配合比设计、冷却管降温及双掺技术等多项措施,成功地进行了承台大体积混凝土的施工,完成了施工生产的需要,同时积累了施工经验。
Combined with construction works of main pier bearing platform of continuous bridge overpass Yiyang expressway of Zhumadian Bridge in Shijiazhuang-Wuhan special railway line for passenger transportation of China railway 18th bureau,successful construction experiences of platform mass concrete under medium-high temperature weather conditions and complicated geological environment conditions are summarized.Many measures including optimization mix proportion design of concrete,cooling with pipe,double-mixing technology and so on are adopted,which complete the requirements of construction production and accumulate experiences for similar works.
