Registration: before Jul. 30, 2009. HydrOu is an Engineering Consulting Engineers. CFRD International Society is affiliated to HydrOu http://www.vncold.vn/ICOLD2010. However HydrOu is completely independent of CFRD International Society. HydrOu welcomes you to join in HydrOu activities and make win-win cooperation now or in the future Mr. Chen Qian Managing Director—HydrOu China ____________________________________ Contact: Mr. Far Young Deputy Managing Director—HydrOu China E: ywhs@msn.com F: 86-717-6721379 T: 86-717-6722137 W: www.hydrou.com A. Why to hold this discussion HydrOu Expert Team has carried out technical consultation free of charge by emailing since Feb. 2008 around the world CFRD field. Lots of original design proposals and original construction designs from outside of China have been sent to HydrOu Team involving with gradation of rockfill material, application of soft stones , treatment of thick alluvium, design in seismic area, etc. Many technical problems have their universality to be discussed. Many facts show that some conventional practices exist in current construction of CFRDs, which have been superseded in China because of potential safety hazard to the built CFRD dams. Modern CFRD dams to be constructed with update CFRD design and construction concepts would shorten the construction period, resulting in greater investment reduction. The best solution for dam builders to response the current global economic crisis is to cut down the investment for the proposed dam projects or CFRD dams under way by shortening construction period. To shorten a construction period and also to insure the construction quality of a CFRD project will depend on the update key technology for CFRD construction approved by construction practices. HydrOu will send top CFRD experts to join in the discussion. B. What to discuss 1. Optimal design principle of CFRD dam body 2. Chinese design and construction concept for CFRDs 3. Possible Harm of conventional practices on the built CFRD dam 4. Measures for cutting down investment 5. Q&A—Questions and answers about current CFRD construction C. Who should attend 1. CFRD expert to publicize specific technology and experience for CFRD construction, seeking international co-operation opportunity 2. Designer to exchange update design plan so as to slam the door for the used degn ideas 3.
