| 摘 要： | 通过对广州大学城软土样基本物理力学指标的室内试验和原位测试数据的数理统计分析,获得了软土的物理力学参数统计值,进而获得了大学城软土的工程地质特性。应用最小二乘法对软土的物理力学指标进行了线性回归分析,得到了指标间的线性相关方程,并应用相关系数的方法来检验相关的显著性程度。统计回归分析成果可为软土物理力学指标间的相互估算做参考,也可为相关规范的修订提供依据。

| Abstract: | 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. |
