巴帕南水闸闸墩整体浇筑温度应力研究 - In order to simulate the construction process and the effect of concrete pouring temperature and outside temperature on temperature field and thermal stress field in the dam , temperature field and thermal stress field are calculated layer by layer . the calculation step during construction is 0 . 25 day , and during operation the diffusion of hydration heat of concrete is over and elastic modulus is basically stable , changeable step is used
为了研究施工进度、混凝土浇筑温度、外界温度对坝体温度场和应力场的影响,按碾压混凝土施工方法每浇筑一层(层厚0 . 3m ,浇筑时间6小时)计算一次温度场和应力场,这样,施工期计算步长为0 . 25天,运行期因混凝土水化发热已结束,且弹模基本稳定,故采用变步长计算。 - ( 2 ) the stress caused by heat of hydration during construction is mainly distributed in the beams , and girders and stress in slab was smaller ; during service process , the stress caused by difference in temperature in different seasons is mainly distributed in bottom components ; the stress caused by difference of inside and outside temperature is mainly distributed in peripheral components of building ; the stress caused by difference in temperature due to sunlight is mainly distributed in the components exposed to the sun . ( 3 ) the control methods brought forward such as setting the reasonable stripping time reducing cast temperature of concrete setting after - treatment joint inflicting prestress arranging steel for construction requirement and so on are effective and their application may be extended
