“…For sluice concrete cracking problems, many scholars have carried out temperature control and crack research. Such as Zhang [7] used the finite element method and the cooling water technology to research winter temperature control measures of Shandong Liujiadaokou sluice, and achieved good results; Wu [8] used the ANSYS finite element analysis software to research the sluice temperature field and stress field in the cold, high temperature conditions; Zhu [9] researched the sluice pier cracking mechanism thought pier temperature difference between the inside and outside walls of concrete foundation and shrinkage are the main reason of cracks; Wang [10] studied the surface of the insulation, internal cooling, foundation strength, climate and other environmental factors on the pier cracking mechanism. This paper carries out research on Henan plain sluice concrete structures to provide reference in the region sluice crack.…”

For sluice concrete structure is more complex due to constrained by the base effect and upper structures, with the purpose of temperature control, we carry out the simulation analysis of temperature and stress during the construction of pier concrete structure. Taking a sluice project as an example, use the method developed by Thermo finite subspace model simulation procedures, the finite element model of pier structure is built with high precision. The results show that the cracking risk is relatively small and prone to surface cracks for baseplate; during construction period, much more attention should be payed to the high temperature difference between day and night, and to the insulation work at cold and windy weather; the key problem is that the middle pier which faces relatively great cracking risk, and necessary temperature control measures should be adopted.
