| Abstract: | Research purposes:In combination with the construction practice of high strength concrete pier of pre-station engineering of Fuzhou-Xiamen Railway,the analyses are made of the causes for the crack of high strength concrete and the measures for control of concrete crack are presented to keep the high strength concrete from crack from the areas of pier structure,raw materials,matching ratio of concrete and construction technology. Research results:The construction cost can be reduced,the construction process can be speeded up and the construction quality can be ensured,if the crack of high strength concrete used for pier is controlled effectively. |
