We can calculate the value of reliability index and failure probability by a new reliability analysis method of slope stability. But how can we test the correctness of this new method by laborotory test or in situ test?
I want to analyze the slope stability of a simple slope using FEM. And the slope has been analyzed by LEM. One of the known data is the coefficient of water pressure. If i want to compare the results of these two method, how can i consider the coefficient of water pressure in FEM?
I think elasto-plastic stiffness matrix will be unsymmetric when yielding function and plastic potential function are not the same one. Am I right?
If it is true, how to solve the equations in nonlinear finite element anasysis?
Dear friends:
I want to know if there are some differences among the stability of a natural slope,a cut slope and a fill slope whose size and soil parameters are all same.
If i analyse their stability without thinking of the consolidation of the soils, are their stability same?Or,I want to know...
Hello
I'm using FORTRAN to calculate the reliability of a geotechnical engineering structure,and I need the results of the finite element analysis. But I don't know the method of how to make use of the results of ADINA or ANSYS in FORTRAN code. Can someone help me?
Dear friends:
I'm using some finite element softwares such as ADINA\ANSYS to analysis the stability of a slope. Although I can calculate the stress and strain of each elements,I don't know how to calculate the whole safety factor of a slope.Do I need to draw many slip surfaces and calculate each...
Dear friends:
I'm learning the use of ANSYS to perform a reliability analysis. But I met with some questions that disturb me very much.These questions are:
1.How to perform a reliability analysis for each elements? I know the method to calculate the failure probability of one element by using...
