根据现场实测沉降曲线计算总沉降和工后沉降的方法有多种,但计算结果差异较大,多年工程经验表明,双曲线法计算的沉降量值普遍大于其他方法计算的沉降量值。本文结合一个工程实例,分析了常规方法计算总沉降量时差异较大的原因,并通过建立数值模型模拟分析软土地基的沉降发展过程。

There are many kinds of method to calculate the total settlement and post construction settlement based on the field measured settlement curve.However the results are quite different.Years of engineering experience shows that the settlement value calculated by hyperbolic method is generally greater than other methods.In this paper,an engineering example is given to analyze the reasons for the large difference in the total settlement calculated by the conventional method.The settlement development of soft soil foundation is analyzed by numerical simulation.
