摘要
基于孔压静力触探原理,结合相关文献资料的分析方法来计算软土固结系数的主要过程。以大连湾跨海工程为研究实例,结合工程实际对其进行孔压静力触探试验,其结果为:实测数据远高于室内试验所得数据。所以对现场进行了大量的分析计算,得到大量数据,通过对照分析两组数据,发现有所关联且具有一定的线性关系,通过回归分析,给出回归方程。
The consolidation coefficient of soft soil is calculated based on pore pressure static cone penetration principle combining with related documents and the pore pressure static cone penetration test is carried out based on sea-crossing project of Dalian Bay combining with engineering practice. The results show that the actually measured data is far higher than that of interior test. Hence, large quantity of analysis and calculations are conducted on site to obtain large number of data and two groups of data are compared and analyzed which are found to be correlated and have a certain linear relations. Finally, the regression equation is given through regression analysis.
