土体侧限压缩模量简易计算方法及其应用

地基土的模型已不下数百个，但真正能反映土体真面目的几乎没有，其原因是土体本身太复杂。要想全面地考虑土体本构关系，其模型参数将会多得难以在实践中应用。因此，从实用角度出发，应建立简单的（包括形式和参数的可得到性）、能够反映研究问题主要矛盾的模型。结合建筑工程关心的沉降问题，根据e-p曲线和e-lgp曲线的关系，建立了与土体竖向应力有关的土体侧限压缩模量的计算方法，并假定泊松比根据不同的土类，确定为不同的常量，从而，可以较为简单地计算土体的沉降及其应力，工程实例计算结果表明：该方法具有合理性。

A simplified calculation method of oedometric modulus of soil and its application

There are hundreds of soil model, but there are no model which can describe the true features of soil because soil is too complex. In order to describe all the characters of soil, we have to join lots of model parameters. However, too many model parameters of soil make the model can not be used in practice. From engineering practice, the best model is that its form including to obtain the parameters is simple, but it can describe the concerning problems. Based on the relationship of e-p curve and e-lgp curve, a simplified calculation method of oedometric modulus of soil is established. And Poisson ratios of different kinds of soils are assumed different constant values. So a simplified soil model, which can describe the settlement and the vertical stress accurately, is presented. The calculated results of engineering case show the rationality of the method.
