| 摘 要： | 文中通过收集已完成的近40个海洋平台的工作报告中的钻孔资料,通过室内振动三轴试验,整理出372渤海原状土样动力学测试的原始数据,进行归纳分析,利用数理统计学的方法给出渤海海域内不同类型土体、不同埋深的动剪切模量比和阻尼比随剪应变变化的平均曲线及推荐值。并以三种典型土类为例,将统计值与规范值、推荐值进行比较分析,得到了非常有价值的结论。本文的结果可供渤海海上工作无试验资料和今后修订渤海海上土动力学参数规范值时参考使用,对工程抗震和地震安全性评价也具有一定的借鉴意义。

| Abstract: | In this paper,the research is sorted out more than 372 original data tested by undisturbed soil sample dynamics of the Bohai Sea by means of collecting the borehole records in the work reports of nearly 40 ocean-platforms which had been finished.Using the mathematical statistics method,the article provides the average curves and recommended values of the dynamic shear modulus ratio and the damping ratio varied with the shear strain for different soil types and different depth of the Bohai Sea.Furthermore,th... |
