Lacustrine Deposits Of Soft Base Of Embankment Settlement Characteristics And Processing Techniques

For the high-class highways builded on the area of lacustrine deposits soft soil, because earth fill of subgrade is very high and construction period is very short, the controlling of subgrade stability and settlement are the two key techniques. Based on the treatment engineering of 26 kilometers lacustrine deposits soft soil foundation in Han-Sha sect of Yi-Huang freeway, the paper, through the means of centrifugal model test and field observation, establishes mathematical analysis model, completely and detailedly researches and analyses the stability of lacustrine deposits soft soil foundation and the rule of settlement, guides the large-scale construction of Yi-Huang freeway 26 kilometers soft foundation treatment, educes the settlement characteristic and the rule of lacustrine deposits soft soil subgrade, summarizes the scientific measure of effectively controlling the stability and settlement of such kind of foundation.
