Abstract
To satisfy the demand for position correction of prefabricated U-type beams in a subway line,the correction scheme based on jack-ing technology is suggested through the scheme comparison.A complete set of jacking method is established,which specifies the key technolo-gy during the process of jacking correction.Practice shows that the suggested technology has the advantages of high resetting precision,fast construction progress,obvious economic and social benefits,and is worth further popularizing and applying.关键词
