为研究高速滑坡超强流动性及沿程侵蚀问题,在Goren热-水-力耦合模型的基础上结合滑坡侵蚀率公式,构建了考虑沿程侵蚀影响的1维高速远程滑坡热-水-力耦合物理模型,提出了有限体积法隐式格式与TDMA耦合算法,对高速滑坡运动热水力耦效应及侵蚀效应进行数值模拟。结果表明:高速滑坡运动过程中热水力耦合效应提升了滑坡的流动性并显著影响滑坡的沿程侵蚀作用。 |

In order to study the high mobility behavior and erosion effect of landslide,the erosion formula was combined with thermo-poro-elastic model to construct the one-dimension long-range landslide model.The coupling numerical method based on the implicit scheme of finite volume method and TDMA algorithm was proposed to simulate the thermo-poro-elastic effect and erosion effect during the movement process of landslide.Numerical results indicated that the thermo-poro-elastic effect enhanced the landslide mobility and affected landslide erosion significantly. |
