The Interaction And Optimized Designing Of Slope And Retaining Structure

Every typical port in Three Gorge Reservoir is high steep slope. The stability of port's slope is not only related to the operation of port, but also to the living of local resident with the evaluation of river fluctuated. Applying exiting theory of engineering design and usual technique of construction cannot be satisfied with the demand of slope's stability. Although many scholars and engineers had been studied the retaining structure and slope's deformation further, there are still too much questions about the rules between retaining structure's design and slope's design should be resolved.A series of large projects are related to the interfaction between high steep slope and retaining structure. It is difficult for people to design it and few people has been studied it futher in this field. It is great significance for us to study the interfaction between high steep slope and retaining structure because of analysis of this field is about national wealfare and people's livehood. This paper's prime aim is the study of interfaction between high steep slope and retaining structure of typical port in Three Gorge Reservoir through numerical simulation method. It simulated geologic condition of typical port in Three Gorge Reservoir and slope which was supported by Anti-slide piles and retaining wall by FLAC3D. Then we can draw some conclusions as follows:Changed retaining wall's size, changed anti-slide pile's diameter, changed pile's location and changed pile's length have great effect on slope's displacement and retaining structure's inter force.We can get the deformation rules of slope and inter force rules of structure under different retaining structures through the simulation of two schemes. Furthermore, those rules can instruct the relation between slope retaining structure's design and slope's stability. So the results of this thesis have great value for later simulation and other research.
