To quickly assess the difficulty of the text, read a short excerpt:
The foundation contacts should be examined for any evidence of interaction with the foundation. The concrete surfaces should be examined for leaching and de- terioration caused by weather, unusual or extreme stress, alkali or other chemical reaction, erosion, cavitation, temperature dif- ferential, vandalism, etc. The concrete should be examined for indications of growth (swelling usually is caused by alkali reac- tion) such as pattern cracking, cracking at embedded metalwork, and differential ...movement. All cracks and spalls on the dam faces and in the galleries should be examined. Gallery cracks should be examined to see if they coincide with face cracks. Cracks and spalls noted during past exa- minations should be evaluated for any change of condition. New cracks and spalls should be noted and examined to determine the 53 SAFETY EVALUATION OF EXISTING DAMS type, such as tension or crushing, and the reasons for their exis- tence. Photographic documentation of a crack or spall condition aids in evaluating the changes from one examination to the next.
