Statistical analysis on engineering geological properties of soft soil in Guangzhou College City

The engineering geological properties of soft soil in Guangzhou College City were studied.To do the research,mass of indoor tests and in situ tests about the soft soil were made and mass of the indexes of physics and mechanics of soft soil were obtained.The test data were analyzed by the method of mathematical statistics to get the main statistical parameters of soft soil in Guangzhou College City.The engineering geological properties of soft soil were gained by analyzing those statistical data.To further study and analyze the engineering geological feature of soft soil,correlated statistics analysis was applied and the linear regression analysis between the physics and mechanics indexes was performed by the least square method.Therefore the equations of linear regression between the indexes were established.The method of correlation coefficient was applied to check the significance of correlation degree.The achievements of statistical regression analysis can be consulted when the indexes of physics and mechanics need to be estimated,which can also provide for reference when correlated standards and codes need to be modified and reedited.
