The Slope Rate Optimization Design Review Of Xingfen Highway’s Cutting Slope

This Paper base on highway administration in hebei province science and technologyprojects:"the class of the soil cutting slope stability analysis and supporting technologyresearch." Class characteristics of the soil slope is different from a simple homogeneous soilslope and rock slope, but somewhere in between, the characteristics of both the soil slope,also has the characteristics of rock slope. Highway slope sliding problems become the mainfactors affecting highway safety in recent years.After the completion of Xing fen highway deep cutting，a sliding phenomenon happenedamong cutting slope, engineering may be due to the construction process has largerdisturbance on the stress field, due to the first cutting slope’s ratio is a little larger, slumpcould be happened in heavy rain, so decided to cut slope, in order to explore the the mainreason for the slump and whether the secondary cutting slope is stable, this article selects theappropriate discrete element analyzed software to simulate the slope.Therefore this Paper using discrete element software to establish two.dimensionaldiscrete element numerical model under different slope rate, the analysis of different rate ofthe downhill body changes the elevation point displacement, stress of the rock mass and thejoint and the changes in the elevation point displacement under the condition of seePage andjoint shear stress change, it is concluded that two cutting slope and the safety factor of slopeunder seePage condition, finally sums up the main causes of slope sliding.According to the results of the comParative study, this Paper Xing fen highway slopequadratic optimization design the rate of of cutting slope’s change in assessment, provide areference for other rate of slope’s optimization design, has a guiding significance to theconstruction of similar projects.
