| 摘 要： | 首先回顾了基于孔压静力触探(CPTU)测试确定前期固结压力的方法,通过连云港海相粘土场地进行的CPTU试验资料,以室内固结试验得到的前期固结压力作为参考值评估了经验方法预测前期固结压力的有效性。最简单的方法是直接建立前期固结压力和净锥尖阻力的关系,同时也是最有效的方法。

| Abstract: | This paper presents a brief review about the existing methods for interpreting pre-consolidation pressure in clays from piezocone penetration tests.The empirical methods are compared and evaluated on the basis of the piezocone tests data on marine clay sites in Lianyun Port,while the pre-consolidation pressure determined from oedometer tests were used as the reference values.The simplest method is the method directly relating the pre-consolidation pressure to the net cone tip resistance.The study finds that this method is the most effective method. |
