Experimental study on frost area of peat soil roadbed settle-ment deformation

Abstract

Abstract.Aiming at the problems of disease and adverse geological section of peat soil, the entity test project, the settlement deformation law of peat soil roadbed is analyzed, and the theoretical calculation results and the actual monitoring results of test section compares the total longitudinal settlement. Due to changes in layer thickness, as peat soil, lead to obvious differences in time on the settlement of turfy soil; peat soil foundation settlement amount and thickness of peat land basic positive proportion; according to the long-term observation, the test project focused on monitoring and sampling survey, data analysis and sorting, visible different turfy soil ground treatment measures have advantages and disadvantages. Therefore, should be combined with the climate characteristics in the actual project, for the completion of prediction of peat land area used for roadbed settlement provides theoretical guidance and reasonable solution of peat soil roadbed.
