Three dimensional deflections of a concrete arch dam due to solar heat in a daytime on March, July, and November were measured by the system consisting of two sets of theodolite with the launcher of a laser and the device which receives the laser. The thermal analysis using finite element method has been conducted to compare the measured deflections and estimate the behavior of arch dam by solar heat. It has been cleared that the obtained results from the thermal analysis estimate the behavior of all over the concrete arch dam with enough accuracy.
