摘要
介绍了软土地基沉降预测中常用的指数曲线模型和双曲线模型。通过工程实例,应用指数曲线模型和双曲线模型对沉降观测数据进行了最终沉降量和后期沉降的预测,讨论了两者的适用性和局限性,证明了指数曲线模型比双曲线模型在预测最终沉降量和沉降曲线拟合方面更加准确和适用。
The index curve and hyperbola curve models often used in forecasting settlement of soft soil foundation have been introduced. Taking an engineering project as an example, the final settlement and posterior settlement have been forecasted with index curve and hyperbola curve models for observed settlement data. After the discussion of applicability and limitations of both two models, it is concluded that the index curve model is more accurate and applicable in forecasting final settlement and settlement curve than hyperbola curve model.
