摘要
1995年甘肃永登5.8级地震引起了黄土山梁的酥裂震陷,说明黄土在较小震级下也会有失稳现象.利用三维土体的有限元计算方法,对永登地震山体变形进行了计算机模拟,并定量地分析了变形的机理.
The subsidence and failure of loess hills induced by Yongdeng MS5.8 earthquake in 1995 indicats that damage exists even in moderate strong earthquake in loess area. The 3D FiniteElement method and computeradded analogue are used to study and analyze the mechanics of deformation on loess hill in Yongdeng earthquake.
