수착아국공로건설적신속발전，공로교량중대체적혼응토월래월다。대체적혼응토재요축후비상용역산생렬봉，엄중영향교량결구안전화정상사용。본문결합시공경험급상관기술규범，간술료대체적혼응토렬봉형성적원인급방치판법。
With the rapid development of highway construc-tion in our country, there is more and larger volume concrete in highway bridges. Large volume of concrete is very easy to produce cracks in pouring, seriously af ecting the safety and normal use of the bridge structure. Combined with the constru-ction experience and relevant technical specifications, the au-thor describes the reasons and prevention measures for the fo-rmation of cracks of large volume concrete.
