结合使用三维有限元法,对某溢流坝闸墩的裂缝成因进行分析和探讨。结果表明,在正常工况荷载作用下,闸墩不会产生裂缝;浇筑时的温度应力及混凝土的施工质量达不到要求是闸墩裂缝产生的最可能的原因。
Combined with the use of three-dimensional finite element method, the cause of cracks in a spillway pier is analyzed and discussed. The results show that under normal conditions, cracks will not occur in the pier; temperature stress during pouring and failure to meet the construction quality of concrete are the most likely causes of cracks in the pier.
