在软土地基上修建高等级公路,路堤的稳定性就显得尤为重要。工程实践表明在大量的软弱土层上修建公路时,滑坡事故经常发生,造成滑坡的根本原因是在软弱土层上施工过程中,地基中土体的应力状态发生了变化,土体内部的某个面上的剪应力达到或超过了它的抗剪强度,稳定平衡遭到了破坏。通过工程实践中稳定破坏的原因加以分析,并提出防止土体滑坡的一些措施。希望与更多同行进一步的研究探讨。
The construction of high-grade highway on soft soil foundation, the stability of the embankment is particularly important. Engineering practice shows that landslide accidents often occur when a large number of soft soil layers are constructed. The basic reason for the landslide is that the stress state of the soil in the foundation has changed during the construction on the soft soil. The shear stress on one face meets or exceeds its shear strength, and the stable equilibrium is destroyed. Through the analysis of the causes of the steady destruction in the engineering practice, some measures to prevent landslides are put forward. Hope and more colleagues for further research.
