The fore-and-aft changes of stress with the optimization at the front of pier and the crest wall at the position of water-seal of concrete gravity dam are compared in accordance with the engineering cases.The analytical results show that the position of water-seal of concrete gravity dam with high water head will cause a larger influences on the stress at pier.The stresses at pier and crest wall will improve obviously when the position of water-seal is moved back.
