Liantuo Channel regulation and reef blasting project is located in Liantuo River section between two dams，the main purpose of which is to adjust the reef blasting area from flat slope to longitudinal ladder slope，to expand the water flow area of the rapids thereby reducing the velocity and slope，level the shoreline，increase the depth of the shore，and adjust the river bed section shape to improve the bad flow pattern.However，the work amount of LT7 reef blasting area in the reef blasting is very large，and the work amount of single beach regulation blasting currently ranks first in the inland waterway regulation projects.This paper studies the construction layout，construction layering method and construction ship equipment selection under the deep water drilling and blasting construction，and determines the construction methods of different zones in this area.The actual effect of channel regulation shows that the channel flow condition has been improved obviously，which proves that the construction method adopted is reasonable and effective.The research results can provide a theoretical basis for the implementation of the reef blasting project in Liantuo section，and can also provide a reference for the subsequent regulation of other beach sections.
