| 摘 要： | 收集天津新港海域16个工程323个淤泥原状土样的物理力学指标,利用数理统计和概率论的方法,分析研究了该地区淤泥抗剪强度指标φ、c的变异特性,得到了物理指标与压缩指标、强度指标间的统计关系及经验公式,并利用A-D法对φ、c的概型分布进行检验。其成果为天津地区软土土性指标的合理取值提供了参考和依据。

| Abstract: | 323 physical and mechanical indices of undisturbed sludge sample in 16 engineering projects in Tianjin xingang port were collected.By means of mathematical statistics and probability theory,the variability of shear strength indices φ、c was studied,and the statistical relationship and empirical formulas for physical index,compression index and strength index were obtained.The A-D test of the probability distribution model of φ、c was carried out.The study results provide a reference and basis for defining reasonable value of geotechnical parameters of soft soil in Tianjin district. |
