Settlement Of Embankment Calculate And Analyze On The Contrary On Soft Soil Foundation

Along with the fast development of the our country capital construction, build the high grade highway to increase increasingly on the soft soil foundation. Settlement of embankment on soft soil foundation have transform big, the asymmetry strong and settlement last long etc. characteristics, these factors affect the long-term stability of road , go the car comfort and safetiesThis original set out from the property of the soft soil and transform the principle , Analyzed the applicability of various theories, about the research to the existing calculation method, From the calculation of method and Analyze on the contrary the both side to begin to carry on the analysis and estimates settlement of embankment on the soft soil foundation ,The original is that no equal interval GM (1, 1) method model for forecast settlement of embankment is built according as the building principle of grey theory model.By means of process no rule of data sequence make equal interval data sequence,put forward intercalary value method and spline curve method that transform no sequencing theory. Utilizing Matlab7.0 to open up settlement forecast system of the embankment.Afterwards carry on the differential fit to the data,again will obtain to draw near the most splendid settlemen development tendency according as analysing and contrasting settlement curve. Thereby can progress the more exact forecast of embankment settlement on soft soil foundation, the use and perfecton no equal interval equivalency information model GM theory on this foundation , Made use of to provide to draw lessons from for the engineering aftertime.Contrast of this text analysis about forecast settlement of embankment on soft soilfoundation on GM theory and logarithm curve theory and twin curve theory, put forward Applied the condition the evaluation about the each method, Also verified these three kinds of applicabilities . Put forward the good suggestion about forecast settlement of embankment on soft soil foundation. This text selected by examinations the estimate model and method is reasonable on forecast settlement of embankment on soft soilfoundation. Toward prevention settlement of embankment and guarantee the good operation quantity of highway have important theories value and economy value and engineering actual meaning.
