摘要
通过特定加、卸荷方式的一维固结试验,模拟了软基在等载预压、超载预压模式下的变形过程。试验表明,软基路堤施工过程中的分级加荷,对于全部荷载长期作用的变形过程,不足以对总变形产生较大的影响;对于有超载参与的预压过程,当超载作用时间小于完成等载变形要求的最佳时间时,对总变形量不会产生影响,否则会使得总变形量增大。
In this paper, the deformation process of the 1-D consolidation test with loading and unloading. The the soft clayey foundation are simulated though results of the test show that stage-loading in the proceed of the embankment construction is not sufficient to affect the total distortion in the long course of deformation with whole load; during the process of superimposed loading,if the loading time is less than the prime time of equal preloading, it will not bring any influence to the total deformation,else the total deformation will increase.
