【摘要】 本文总结分析了碎石桩处理由可液化层和软土层交互组成地基的沉降历时曲线线型特点,沉降量与填土高之间关系,沉降历时曲线线型特点及硬壳层和软土层厚度对沉降变形的影响,同时也讨论了沉降速率与填土速率之间的关系。该分析成果能够估算碎石桩处理地基的沉降,并解释了硬壳层和软土层厚度变化对沉降变形的影响。更多还原

【Abstract】 Gravel piles are used to improve problematic ground that is composed of the alternative layers of liquefiable soils and soft clays.The settlement-time curves of gravel-pile-treated ground are discussed.The influential factors on the settlements,such as embankment fill height,crust thickness and the layer thickness of soft clays,are investiˉgated.The relationship between settlement rate and construction rate is also discussed.The analysis results obtained in this study can be used for predicting the settlement of gravel-pile treated foundation.更多还原
