| Abstract: | In the view of the settlement deformation in a embankment deep thick soft soil subgrade, and taking the one-dimensional consolidation differential systems and the measured settlement course as the basis, the article analyzes the forecast model of one-dimensional consolidation settlement and approaches the identification and filtering wave of the forecast model. After the analysis and measurement of the settlement course line, the article puts forward the settlement forecast method by sections. Its accuracy ... |
