Back Analysis of Road Foundation Settlement Forecast Based on Soft Soil Structural Damage

Abstract

Towards a more efficient prediction of settlement after work, the elastic mechanical characteristic values of soft soil should be adjusted in view of soft soil structural damage or disturbance. Using back analysis of model parameters based on calculation of consolidation settlement, the subsidence trend and reasonable forecast can predict and compare the measured data and theoretical values. The results show that soft soil structural damage should be considered in predicting the settlement of soft soil subgrade. The predicted values and the inversion parameters were closer to the measured values with a series of feedback processing. The design and construction process are closely linked, serving as the basic and most important component of dynamic design.
