应用实测资料推算土堤总沉降

Estimation of Total Sink of Dike with Measured Data

结合木兰溪防洪工程长达4年的安全监测实例,用两种常用的利用实测资料推测总沉降量的计算方法,对测得的四个沉降量最大断面处的最终沉降量进行了推算,推算结果表明,当荷载稳定后沉降观测超过一年的断面,适合用三点法计算;荷载稳定后沉降观测在半年左右的断面,则用双曲线法计算较合理。

This paper,in combination with the instance of monitoring Mulan rivulet for 4 years,uses two often-used measured data to calculate the total sink,and calculate the final sink of four typical dike sections. The results shows that three-point method is more suitable for over 1 year＇s observation after stabilization of loading,and hyperbolic method is more suitable for over half a year observation after stabilization of loading.
