Research On Settlement Speed And Stabilization Of High Earth Fill Sub-grade

This paper, as for the contradiction happened in design, construction, acceptance check when the quality of the project was needed and the building speed is different in every section of the road, the residual settlement A h is needed to be less than the standard value, launches theproject------the analysis on the settling velocity o f high earth fill sub-grade and the study ofstability.This test of the study including lots of field investigation and indoor experiments has been carried out according to the operating steps and test program of the test Methods of soil for highway engineering .The results can be taken as the reliability base of correctly dividing sub-grade settlement.The indoor experiments and field investigation are applied to find the settlement speed of high earth fill subgrade. The steadiness of high earth fill sub-grade is discussed with random finite element data analysis method. The rational depth of single layer, method of compaction, standard of compaction is provided. Construction mechanic is summed up to keep the quality of sub-grade.
