The Wudongde and Baihetan arch dams are two super high arch dams under construction at the same time in China. The dam site is located in the windy, dry, hot Jinsha River valley. The dams are made of low-heat cement. This project models the temperature control and crack prevention during the pouring process, the dam and foundation deformation control with water storage, and the safety of long-term operation. This article focuses on the key technical issues involved in simulating the dam construction process with the intelligent construction system used for these dams, the key problems in the simulation dam construction process, and the key points in creating dam construction simulations. The experience gained in developing these two engineering dam simulation was used to identify the problems that need to be solved for future projects.
