Simulation Study on Transverse Joint Opening of Dongzhuang Arch Dam
During the construction period of high arch dam,concrete pouring,temperature control,joint grouting and flood holding are four integral links,interlocking and restraining each other.Only when the pouring top elevation,cooling zone top elevation,irrigated area top elevation and water storage elevation are coordinated,can the construction of high arch dam be carried out smoothly as planned.There is no successful case for the scheme decision with the transverse joint opening as the core of high arch dam,and the transverse joint opening monitoring during construction can only solve the existing problems in the past,but can not predict the future.It is particularly important to predict the influence of the transverse joint opening and closing on the dam construction by using the numerical simulation of the transverse joint opening and closing of high arch dam.The transverse joint opening of Dongzhuang Water Conservancy project is simulated to simulate the concrete pouring process,temperature control process,grouting process and water storage process,so as to predict the stress-strain state of the arch dam during the construction period.
