摘要
官厅湖特大桥大体积承台混凝土的施工中 ,不设置降温水管 ,仅从混凝土本身组成和配合比以及施工后的养护措施两方面加以控制 ,解决较大体积混凝土施工中易于出现的裂纹问题 ,同时也降低成本 ,获得较好的经济效果 。
In the construction of extra large concrete bearing platform of Guangting Lake Bridge,no temperatuze relief pipes were installed.Only two mearases i.e. the comparction and curing after placement were taken.With such measuzes the cracks likely appear during placement can be avoided,the cost can be lower and a betten economical effect can be obtained.It would be a very suggestive for concrete construction.
