一种预测路基工后沉降量的方法

根据沪宁高速公路长期的工后沉降观测资料，总结出地基沉降固结的规律；在荷载稳定时，沉降曲线在ｓ￣ｌｇｔ坐标中接近于抛物线。据此提出了一种简单易行、能够比较准确推算未来沉降量的方法，即根据一段时间的实测沉降量，结合位移反分析方法，推算出方程的系数，即可得到沉降方程。工程实践证明，文中所提方法克服了常规双曲线等方法推算结果误差较大的缺陷。

A New Method to Predict the Settlement of Embankment

In the article summarised is the law of consolidation settlement according to the long term survey data of the HU NING highway.It is considered that the settlement curve is close to the parabola in the s lgt coordinate when the load is stable.On this basis,a simple method is proposed to predict the future settlement accurately.Based on the survey data,combined with the reverse analysis of displacement,through calculation of the coefficient of the equation the equation of settlement can be obtained.Engineering practice proves that the result predicted by the present method is more accurate than that by conventional methods.
