the Application of Science Computing Software in Geotechnical Computing
2002, 16(2): 63-66.
[Abstract](67) [PDF 174KB](4)
Abstract:
With development of computer technology and appearance of many science computing software such as MATLAB and ANSYS, which provides new idea and method for geotechnical engineers to solve geotechnical problems. It's worth believing that science computing software will become right hand of geotechnical engineers.
Improvement for the Calculating Method of Single Pile Erect Bearing Capacity
2002, 16(2): 67-69,94.
[Abstract](39) [PDF 314KB](4)
Abstract:
According to the character and extensibility of the ordinary P-s curve,through Prolonging the curve and creating a substitute curvature function,geting a calculating fermula of single pile's ultimate bearing capacity by mathematic method.On the basis of analyzition and comparation,this formula's feasibility is proved.

Data Processing System of Test for Foundation by Forced Vibration
2002, 16(2): 88-94.
[Abstract](46) [PDF 496KB](3)
Abstract:
Testing for forced vibration on simulative foundation needs to collect mass data and to calculate the complex dynamic parameters of groundsoil. In order to change this state, working out a process software DPS 3.0 by using popular Delphiprogramming technology in Windows, this software promots the work efficiency greatly.Providing two examples on composite foundation and bed rock.
the Study of Coarse Materials' Elastic-plastic Constitutive Relation Model
2002, 16(2): 95-99.
[Abstract](28) [PDF 211KB](2)
Abstract:
Through regressing the strength curves of coarse materials in test,establishing a strength criterion (τ=Aσb), based on this yield criterion and elastic-plastic theory,establishing a elastic plastic constitutive relation model of coarse material,which is continuative,no odd and has less parameter,and giving the elastic-plastic matrix D ep.The reasonableness and feasibility of this model are proven by practice.
