Abstract: Inverted siphon buried pipe is used to make across the Luzhu River in the second water source project of Qiandao Lake which is an improvement from the original diversion plan. The original diversion plan would affect the normal operation of highway and would include large amount of compensation for the submergence. By schemes comparison and optimization, the appropriate scale of diversion structure is selected, in which the risk is well controlled and investment is saved.

Key words: construction diversion, diversion period, diversion building, optimal design
