摘要
结合江苏省京杭运河上近几年的几座船闸施工情况,分析船闸闸首底板这类大体积砼浇注时的温度应力,从降低温度应力、提高闸首底板砼本身的抗拉性能以及加强砼早期养护等方面提出温度裂缝控制的施工技术措施。
Based on the situation of shiplock construction in the Grand Canal of Jiangsu Province, the temperature stress of mass concrete construction in shiplock head floor is analyzed, and the control technique of temperature cracks is provided from several aspects, such as lowing down the temperature stress, improving the anti-stretching ability of concrete itself, and strengthening early maintenance for concrete.
