The Analysis based on the Elasticity Theory for the Analytical Solution of Basal Stress
The maximum basal stress of rectangular section enlarged base is associated with basal stress state.At present,the calculation of the base stress of the extended foundation with rectangular section on the bedrock under bidirectional eccentric compression as per Chinese specifications is based on the table lookup and the formula,which is inconvenient and error-prone for batch calculation.In view of the above situation,in the paper,the code for the calculation of basal stress in China is introduced briefly.Then,the analytical results of basal stress of enlarged rectangular section base is analyzed based on the elastic theory in order to obtain the formula for analytical solutions under various stress distribution.The calculation results are compared with those of standard calculation.The result shows that analytical results in this paper are in highly accordance with the standard calculation results in the code,which will be of great importance to promote engineering design in the future.
