Research on the Mechanical Mechanism of the Stability of Semi-filled and Semi-excavated Subgrade Slope
In order to ensure the construction level of highway subgrade,this paper summarizes the types and failure modes of semi-filled and semi-excavated subgrade,and analyzes the selection method of mechanical parameters of filling-excavation interface.At the same time,taking the semi-filled and semi-excavated slope at K2+100 of an expressway connecting line as the research object,the finite element software is used to establish the calculation model,and the influence of filling width,filling material water content,and geogrid layer number on the safety factor and stability of the slope is analyzed.The research results can be used for reference in similar projects.
