船闸边墩属于大体积混凝土，施工前进行混凝土温度应力计算是控制裂缝的关键，而掌握混凝土内部温度随时间的变化是计算结构内部温度应力的前提。现场温度监测和有限元计算得到的混凝土内部的温度变化规律，监测数据验证了有限元计算的准确性，为类似工程通过有限元计算控制混凝土温度裂缝提供了技术支撑。

Side pier of lock is mass concrete. Before the construction of the side pier, temperature stress calcu?lation is important for the crack control, and the internal temperature of concrete with time is of vital important to the calculation of temperature stress inside concrete. Through the comparison of in?situ temperature monitoring and finite calculation analysis of temperature inside the concrete, the accuracy of the finite element calculation is veri?fied by the monitoring data, and it is possible to control the temperature crack of concrete through the finite element calculation data.
