| 摘 要： | 采用有限元方法探讨在人工开挖或自然侵蚀环境下,岩质边坡体内应力场的变化及节理发育形成机理,并采用有限元强度折减法对后缘具有张节理边坡的稳定性影响因素进行敏感性对比分析,进而得出具有非贯通节理边坡稳定性计算的修正解析解.结果表明:卸荷及风化作用导致边坡体由表及里出现应力重分布及应力集中的现象,使边坡后缘由顶部向下发育一簇...

| Abstract: | The changes of stress field and formation mechanism of joint development of rock slope under the condition of man-made or natural environment were studied by finite element method;the sensitivity of factor of slope stability with tension joints was comparatively analyzed by strength reduction finite element method;the analytical solution on stability of non-through joint rock slope was amended.The results showed that the unloading and weathering resulted in stress redistribution and concentration of slope a... |
