Reflections on numerical analysis of geotechnical engineering

The investigation report about the application of numerical analysis of geotechnical engineering in China was introduced firstly.Then the key of analyzing geotechnical problems with continuum mechanics and the current situation of geotechnical constitutive theory were discussed;the developing directions of geotechnical constitutive theory was put forward.Finally,the status of numerical simulation in the geotechnical engineering was evaluated.Through above discussions it can be concluded that,the result of numerical analysis is one of the most important back ground for the engineering judgment of geotechnical engineers in the geotechnical engineering analysis;the key of analyzing geotechnical problems with continuum mechanics is to establish simple and practical engineering constitutive model.Establishing many simple and practical engineering constitutive models and accumulating a lot of engineering experience,numerical analysis can be used in geotechnical engineering from qualitative to quantitative.
