长江中下游地区无温控措施条件下墩墙类结构最优浇筑长度研究

摘要

In recent years,China has planned and constructed a large number of small hydraulic concrete structures.It is very difficult to apply strict temperature control measures on this type of concrete structures.Therefore,ANSYS software is used to analyze the temperature field and stress field of different pouring sizes for pier wall structure without temperature control measures in the middle and lower reaches of the Yangtze River.Aiming at no penetrating cracks in wall,the optimal pouring sizes of pier wall structures are researched.The results have certain reference value to the construction standard and the engineering practice.%近年来,我国规划和建设了大量的中小型水工混凝土结构,此类工程实施严格的温控措施非常困难,因此,本文运用ANSYS软件计算了长江中下游地区无温控措施条件下不同浇筑尺寸的墩墙结构温度场以及应力场,以墩墙结构不产生贯穿裂缝为控制目标,对墩墙结构的最优浇筑长度进行了研究.研究结果对规范制定和工程实践有一定的参考价值.
