International Symposium on Concrete Faced Rockfill Dams

Research Inst. of Water Resources Development Public Corp. Senior Research Engineer Fill Dam Div. Research Inst. of Water Resources Development Public Corp. Chief Research and Design Div. Takizawa Dam Construction OfficeChichibuSaitamaJapan Professor Ph.D. P.Eng.Dept. of Civil Engineering Kyoto University Kyoto Japan

＜正＞For the design of CFRD, it is important to learn the stresses and deformation that develop in the concrete slab and the behavior of the slab during earthquakes. Thus, in addition to the static analysis of the slab, the dynamic analysis was conducted to examine stresses and deformation in the slab during earthquakes. As the result of the static analysis, it was found that the rigidity of the embankment body （Zone B） affects mostly the concrete slab deformation. Further, as the result of the dynamic analysis, it became clear that the concrete slab joints repeat open and close movement to the order of approximately 15mm and the slab moves by following the behavior of the embankment body.

In order to test and guide the maintenance support force system of our army, a research idea based on complex network is supposed on testing maintenance support force system after analyzing the similarity between the system and complex network. Selecting the structure of a system in the different time as the research object, a topology model is established. In the end, we calculate the average path time, clustering coefficient, node centrality, and quality performance, etc. The calculated results validate the correctness of our construction route and carry out the further guidance of the construction direction.
