Analysis and Test on Statistical Characteristics of Geotechnical Mechanical Parameters in Large Urban Engineering Site
The statistical characteristics of the geotechnical mechanical parameters are significant in a large urban engineering site.Two basic issues must be explicated to ascertain the statistical characteristics.1)What principles of geotechnical samples collection has scientific statistical significance for mechanical parameters;2)How to test the statistical significance and distribution model of geotechnical mechanical parameters.By employing statistical theory and statistical experiment methods,some conclusions were achieved that the geotechnical samples collected in the identical stratum by geotechnical investigations conform to random sample normally,and the mechanical pa-rameters have scientific statistical significance;In actual engineering,the statistical significance and distribution model should be verified by run test and x2 test,respectively.According to the conclusion,the test procedure on the statistical characteristics of the mechanical parameters was proposed,which is a guideline for the practical con-struction.
