Management Research on Treatment Measures for Differential Settlement of Tianjin-Binhai Expressway's Widened Subgrade

Abstract:

Control of differential settlement of widened subgrade is one of key pints for the quality control of expressway reconstruction and extension projects and a focus for many scholars. In the paper, the analysis model of the pavement structure stress is built based on character and design parameters of the subgrade and pavement of Tianjin-Binhai Expressway. The control standards for the subgrade and pavements differential settlement of Tianjin-Binhai Expressway are confirmed through analyzing the pavements mechanical response under different differential settlements and treatment measures are taken according to classification of different differential settlements to control the final settlement amount within the preset range, which provides references for renovation and extension projects in future.
