双层超软弱欠固结地基沉降的概率分析

Probabilistic prediction of settlement in double-layerd super-soft underconsolidated ground

  • 摘要: 由吹填淤泥及下卧海相淤泥组成的双层超软弱欠固结地基组合模式在吹填造陆工程中最为常见,此地基模式的沉降与原状海相沉积淤泥层不同,表现出更大的离散性。针对此地基采用概率统计方法对地基沉降进行分析,并通过对实际沉降数据的统计分析依据K-S有限比较法得到地基沉降的最优概率分布模型,应用此模型对地基沉降进行概率预测的结果与实测统计结果相当吻合,说明概率分析的合理性。

     

    Abstract: The pattern of double-layered super-soft underconsolidated ground composed of hydraulic fill and marine mud is the most common situation in land reclamation projects. The settlement of this ground is different from the original marine deposit mud layer, showing greater discreteness. The settlement of the combination ground is analyzed by statistical methods. Through the statistical analysis of the actual settlement data, the optimum probability distribution model for the settlement data is confirmed by the K-S finite contrast method. The results of probability prediction by using the distribution model are consistent with the actual statistics, and the rationality of probability analysis is validated.
