Industry:Engineering
Any large volume of concrete cast-in-place, generally as a monolithic structure. Dimensions of the structure are of such magnitude that measures must be taken to cope with the generation of heat and the resulting volume changes and cracking.
Industry:Engineering
Material spread on the ground to reduce soil erosion and evaporation of water. Any substance spread or allowed to remain on the soil surface to conserve soil moisture and shield soil particles from the erosive forces of raindrops and runoff.
Industry:Engineering
Damage to concrete caused by the effects of a chemical reaction between sulfates in soils or ground water and hydrated lime and hydrated calcium aluminate in cement paste. The attack results in considerable expansion and disruption of paste.
Industry:Engineering
The amount of time between detection of failure or incipient failure and arrival of dam failure flood. It is a function of, and related to, detection, response, breach formation, travel time, evacuation capability, and breach formation time.
Industry:Engineering
A gate consisting of a rectangular leaf mounted on wheels, particularly suited for high head situations. A gate having wheels or rollers mounted on the end posts of the gate. The wheels bear against rails fixed in side grooves or gate guides.
Industry:Engineering
Squared masonry, precast blocks, or embedded stones laid in regular fashion with dry or filled joints on the upstream slope of an embankment dam or on a reservoir shore or on the sides of a channel as a protection against wave and ice action.
Industry:Engineering
The maximum pressure that can be permitted on foundation soil, giving consideration to all pertinent factors, with adequate safety against rupture of the soil mass or movement of the foundation of such magnitude that the structure is impaired.
Industry:Engineering
The angle between the position of a rope or cable at the extreme end wrap on a drum and a line drawn perpendicular to the axis of the drum. The fleet angle is used to indicate how effective or efficient the rope or cable is for raising a load.
