摘要
本文从多方位、多角度对豫西水利枢纽工程泄水建筑物的高性能混凝土裂缝原因进行了全面的分析 ,并通过对观测资料的计算分析 ,得出了高性能混凝土裂缝时的极限参数。同时阐述了水工大体积高性能混凝土在设计。
? This paper gives the overall analysis at different aspects on the reason of the high performance concrete cracks in discharging building of Xiao Langdi Multipurpose Project,and gets the limiting factor that the cracks happened by the calculated analysis on the observation data.As well as it sets forth on the problems shall be paid attention and the precautions shall be taken during the design and construction in hydraulic high performance mass concrete. 〔
