双曲线配合法在某软基段沉降预测中的应用

根据武英高速公路某软土路基实验段的实测沉降资料,应用双曲线配合法推测了该路基段的最终沉降量,并与现场实测的沉降数据进行了比较,结果表明,应用双曲线配合法预测软土路基堆载预压的沉降值虽然较实际值稍微偏大,但该方法预测误差较小,精度较高,适用于本工程。

The hyperbolic curve matching method application in soft foundation settlement forecasting

According to actual measured settlement data of some soft soil foundation of Wu-Ying express highway, the final settlement of the foundation section was presumed with hyperbolic curve matching method, which was compared with field measured settlement data. The resuit indicated that the soft soil foundation piled load preloading settlement value measured by hyperbolic curve matching methed was deviated litter larger than actual measured value, but the previewed error of the rnethod was small, and the precision was higher and was adopted to the engineering.
