摘要
广东省榕江平原地区软土层普遍发育且物理力学性质差,对工程施工建设非常不利。为了分析研究该地区软土各项参数之间的相关性,为日后的软土工程性质研究和岩土工程勘察设计及施工提供参考和依据,通过对大量的土样试验数据进行筛选、剔除异常值后进行统计和分析,得出了该地区软土的各项物理力学指标,并在此基础上对多组室内试验及原位试验软土物理力学性质指标进行对比分析,建立了榕江平原地区多组软土参数间的线性回归方程。通过在该地区的应用,验证了上述回归方程在榕江平原地区具有一定的适用性和可靠性。
Soft soil in Rongjiang plain is very adverse to the construction of engineering because of its bad physical and mechanical properties.The author draws the physical-mechanical indicators of the soft soil in the region through the statistics and analysis based on a large number of soil samples which are drawn after screening and removing outlier,in order to study the correlation of the parameters of the soft soil and provide the basis and reference for the further research on the engineering properties of the soft soil and geotechnical engineering design construction.Then groups of physical-mechanical characteristic parameters from laboratory test and in-situ tests are contrastively analyzed,and the linear regression equations for such physical-mechanical characteristic parameters of soft soil are established.Finally,the author verifies that the regression equation has certain applicability and reliability in Rongjiang plain country.
