高速公路边坡介质的力学性质极为复杂,引起应力及其变形的因素以及应力和应变关系也较为繁琐。传统的边坡稳定性分析理论,大多建立在经验及假设基础上的,经验证,传统计算结果和实际情况差距比较大。由于计算软件的出现,给数模模拟创造了条件,数模模拟将非线性变形考虑到控制要素中,计算值与实际值更为接近,该方法对边坡稳定性分析及治理方案的选择具有很好的指导作用。
The mechanical properties of freeway slope media are extremely complicated. The factors causing stress and deformation and the relationship between stress and strain are also more complicated. The traditional slope stability analysis theory is mostly based on experience and assumptions. It is verified that the traditional calculation results are far from the actual situation. Due to the emergence of the calculation software, the conditions for the numerical simulation are created. The numerical simulation takes the nonlinear deformation into consideration in the control element. The calculated value is closer to the actual value. The method has the following advantages in slope stability analysis and treatment plan selection Good guiding role.
