Study on Scheme of the Second Access of Beijing -Hangzhou Canal and Analysis on Engineering Regulation Measures

The paper describes the study on the alignment scheme of the second access of the Beijing -Hangzhou Canal and Qiantang River Linkage Project ,and extensive analysis is made on the navigation condition of the river mouth at Babao ,it suggests that the Babao river mouth is the best choice on the downstream of Sanbao Lock.The evolution pro-cess of the river bed and control factors of Babao river mouth are analyzed ,then the engineering regulation measures of Babao river mouth are put forward according to comprehensive analysis of historical materials ,model tests and subject re-search ,which lay a firm foundation for the smooth execution of the second access project of the Beijing -Hangzhou Canal.
