Finite element analysis of raft-board long-wide scale of settlement influence for pile-raft foundation;

The geometric model of Al_2O_3 grain is designed based on its crystal character,through ran- domly slicing the grain model with a given slenderness ratio with the emulation slicing system,the grain random section parameter-aspect ratio can be gotten.

Gives a formula to evaluate the buckling coefficient of the compressed flange of lipped channel beams by considering the distortional buckling mode, and presents a set of simplified formulae to calculate the limit values of the aspect ratio α for buckling coefficient not less than 4.

The simulation results showed that the fiber aspect ratio was increased while increasing the mass flow of single hole and decreasing the spinning temperature and quenching initial height,but was considerably decreased while increasing the aspect ratio of the spinneret.

Based on the connecting strength of soil,the effects of foundation length-width ratio on base additional stress and depth of compressed layer were discussed.

This paper puts forward the method for determining length-width ratio of mixer.

A group of correlation output are obtained which is different in the vertical direction and horizon direction by changing the length-width ratio of two same rectangles as the target picture and reference picture.
