Reasearch On The Reinforcement Technology And Stress-Strain Behaviour Of Geogid-rockfill For Qingfengling Earth Dam

Based on the present situation of earth--rock dams in Shandong Province, the author selects the key problem on reinforcement of earth-rock dam. The study on some of typical dams is of wide representative and strong practical. A number of suggestive conclusions are obtained, This paper mainly illustrates the following contents:1 Grasps the domestic and foreign earth-rock dam project theory and in the technical foundation in entire understanding,, analyzes the Shandong earth-stone dam project security survey, the main disease type and the origin, the distributed characteristic and the produced mechanism.2 Has the crucial question to the earth-rock dams which the seepage destroys and governs. The big dam infiltrates the flow field the determination, the attempt introduction limited unit with the method solution which the study of water power unifies, in view of the earth-rock dams main unique feature, studied entire guards against infiltrates the system various links the function and the function, proposed renovates measure which the transfusion destroyed, simultaneously will unify the project is actual to the earth-rock dam seepage analysis the method, the principle, the parameter designation and so on proposes had the universal significance to the Shandong area earth-rock dams reinforcement the opinion and the method.3 Base the analysis of stress-strain, Carries on the key discussion to the earth-rock dams steady analysis method and the landslide government measure, from the earth-rock dams landslide classification, the type, the origin, the government method will conduct and research..4 In this thesis, the engineer advantage of Geogrid Reinforced Earth Dam is introduced, and the working mechanism and the calculation method of Geogrid Reinforced Earth Dam are analzed. Based on the idea the simple method of calculating the seismic stress of Geogrid using the FLAC^3D.5 Through the Shandong earth-rock dams actual reinforcement project correlation question proof research, summarizes the sickness danger reservoir big dam research technique, the proof pattern. The project practice also proved renovated the plant disease reservoir comparatively newly built one big dam is often more complex, gradually got older along with the big scale construction time construction big dam. Without doubt this aspect research achievement has thewidespread practical value and the application prospect.
