摘要
介绍了用PCPT资料判别浅层砂土液化势的方法,并分别用动三轴试验判别法和PCPT资料判别法比较了南海东部海域两个平台场址的浅层砂土液化势判别结果。通过实例验证说明,在熟练掌握PCPT测试方法、资料采集、数据处理和成果解释的基础上,用PCPT判别法判别浅层砂土液化势是可行的。
A method for discriminating the liquefaction potential of sub-bottom sandy soils by using PCPT data is presented .The liquefaction potential of sub-bottom sandy soils at tw o platform sites in the eastern South China Sea is distinguished by using the cyclic triaxial test method and the PCPT method respectively ,and the results from these two methods are compared .It is demonstrated that the discrimination of liquefaction po-tential of sub-bottom sandy soils by using PCPT data can be feasible if the measuring method ,data acquisition ,data processing and interpretation of PCPT are known very well .
