For guiding river bank protection energy-saving and type selection considering the whole life cycle of bank protection project, total energy consumptions are composed of the material energy consumption in production stage, transport stage and construction stage. The mathematical statistical models for energy consumption analyses of each part are given in this paper, comparative analysis on four different kinds of bank protection in Changzhou urban waterway realignment project is conducted as well. The result shows that project energy consumption is significantly affected by the form of bank protection. By comparing with the energy consumption of concrete gravity grouting bank protection per meter, the consumption of balance weight type bank protection is 84.2% of that with 107.3% of that for cantilever type and 67.0% of that for cantilever revetment with greening revetment.
