Research On The Characteristic Of The Expressway Stress And Distortion On Soft Ground

As development of infrastructure in our country, the construction of the freeway and aerodrome way increase freely. During the construction of the freeway, the work of safety monitor of the roadbed stress and distortion provides first-hand information for all kinds of researches, with large numbers of locale data. This is a meaning thing for researching the settlement of freeway and finding the rule of the stress and distortion of freewayThe calculation of the settlement of roadbed is always a difficult problem that puzzles scientific researched and engineers on highway. If you can legitimacy calculate the settlement of freeway, it is important to forecast the distortion of roadbed. This paper combine the first-hand information, we do this work:(1) Establish the project of observation on local, do real work and obtain the first-hand information.(2) Research the pile-soil stress ratio, and find the relation of pile-soil stress ratio and the embankment height, time, the settlement.(3) Clean up the data, find the reality data for analyse the settlement of roadbed.(4) Base on regression theory analyse the data, striving to find the rule of the settlement of roadbed and the embankment height, thickness of crust with high strength and soft clay.(5) Apply the one dimension and more dimension theory to the analyse the settlement of roadbed, contrast this data to the field information striving to find the means to calculation of the settlement of roadbed in reason.I hope our work could find a ideal means for forecast the settlement of roadbed, could instruct the later freeway design and construction.
