Structural Optimization Calculation and Analysis of LSG Reservoir Rockfill Concrete Gravity Dam
To verify the design proposal and optimize the overall design of the LSG dam,mechanical calculations and analysis are needed to evaluate the structural stress of the dam.An elaboration of the dam structural design was made to analyze the characteristic parameters for stability and stress calculation.Taking the retaining dam section as an example,the rigid body limit equilibrium method was adopted to perform anti-sliding stability calculation and analysis on the dam structure.The stress analysis of the dam structure is carried out using the two-dimensional finite element static and dynamic method and the vibration mode decomposition response spectrum method.The results show that the anti sliding stability,self seismic law,and dynamic tensile strength of concrete of the dam all meet the safety requirements.which can provide reference for the optimization calculation of similar reservoir dam structures.
