考虑加筋切向阻力的土坡稳定分析

Analysis of safety of earth slope thinking over tangential resistance on adding reinforced bar

目前在加筋边坡的极限平衡稳定分析中,认为加筋中产生的预应力能约束土体的运动或者能使抵抗土体运动的阻力增加,而对于加筋的切向阻力作用却没有考虑。主要讨论了在加筋土坡稳定分析时,加筋的切向阻力在加筋工程中起到的作用。认为在加筋边坡的极限平衡稳定分析中,也应考虑加筋的切向阻力作用;提出了计算公式,编制了相应的程序,给出了算例。

Now it's widely accepted that prestress caused by adding reinforced bar can restrict the movement of soil mass or make the rsistance to withstand the movement of soil mass raise during the analysis of limiting equilibrium steady for adding reinforced bar,but not thinking over tangential resistance.It's mainly discussed that tangential resistance plays a part in adding reinforced bar project when earth slope steady is analyzed.I think that effect of tangential resistance should be thought over when earth slope steady is analyzed as well.Calculation formula is given,so are related program and example.
