Research On Stress Analysis Of Light Hard Shell And Problems Of Engineering Application

The coastal beaches silt in Our country is high water content, high porosity, little permeability coefficient, buried deeply, low bearing capacity, low shear strength, high sensitivity, long time to consolidate and so on.If diking on the foundation, subsidence, spilling, collapse, Construction difficulties and long construction period are easily appearing, This paper put forward a new type of light scale diking structure. The structure use high strength materials as shell, use light materials, loose material to fill dam, by reducing the weight of the dam to reduce the load of foundation, and optimize design scheme, enhance integral stability, Making the dam in rigid-flexible economic, with the foundation as a whole, reducing and eliminate the uneven settlement of foundation. It played an important role in the sluice cofferdam, man-made island, farm dams to solve the problem of space and site. At the same time the dam (cofferdam, foundation, a retaining wall) design theory research, light and hard-shell dyke dam anti wave research, light and hard-shell dyke dam body and foundation of the whole research, light and hard-shell dyke dam component manufacturing factory and mechanized rapid embankment method research. To establish a set of preliminary calculation theory, using a variety of finite element analysis program to analyze and evaluate the dam’s stability characteristics,reasonable size and Stress influence on the dam body, thus to study the overall stability of the dam and foundation. According to the foundation and the actual situation of the project, the dam type and related geometry, to calculate the stability of against sliding, meeting the conditions of level stability against sliding conditions light cushion zone maximum area determination, analysis of Integral stability, analysis of penetration resistance, analysis of resistance to the horizontal thrust feasibility, Putting forward the Controllable index of engineering practical parameters, which can be used for reference for the similar projects.
