一种填筑软土路基的稳定性控制方法

考虑软土强度随固结度增长的因素,采用有效固结应力法对路基进行稳定性分析,提出了根据现场实测沉降修正理论固结度的方法;同时考虑路基工后沉降要求,确定施工进程中任意时刻的容许填筑高度。所编制的计算程序可用于指导软土路基的安全填筑。

A Stability Control Method for Fill Embankment on Soft Ground

In this paper,the method of effective consolidation stress is adopted to analyze the stability of the embankment,in which the sheer strength of the soft ground is enhanced owing to the increase of its degree of consolidation.The method to modify the degree of consolidation using the tested settlement is introduced.In the process of the embankment construction,the allowable filling height at any time is computed,which meet the demand both of the stability and settlement.The programming can be applied to direct the filling of embankment on soft ground safely.
