新疆某水利枢纽泄洪闸闸墩温控防裂反馈分析

Feedback analysis on temperature control and anti-cracking for flood discharge sluice pier of a water control project in Xinjiang

基于大体积混凝土温度场和应力场的基本理论,结合新疆某水利枢纽泄洪闸闸墩的具体特点,进行温控模拟反馈计算。经分析计算可知,采取减缓早期闸墩混凝土内外温差和采用跟进保温措施是防止闸墩混凝土出现裂缝的有效方法,研究结果可供相关工程参考。

Based on the basic theory of temperature field and stress feld for mass concrete, a feedback calculation for the temper- ature control simulation is made in accordance with the specific characteristics of the pier of the flood discharge sluice for a water control project in Xinjiang. It is known through the calculation that the adoptions of both the measure to alleviate the temperature difference between the inner and the outer concrete of the pier during the early period and the measure of the following-up temper- ature insulation for the concrete are the favorable methods to prevent the cracking of the pier concrete, and then this study result can provide references for the related project concerned.
