【摘要】 我国是地震频发的国家,对有抗震要求的土钉支护不但要进行静力稳定性分析,还应进行支护结构动力响应分析。通过对某基坑土钉支护进行的有限元模拟,研究了土钉轴力在地震荷载作用下的变化规律。结果表明,在地震荷载作用下,土钉轴力分布呈现非均匀非线性变化,且基本呈增大趋势。更多还原

【Abstract】 Seismic related hazard is frequently encountered in some areas of China.Therefore,in addition to the static analysis of the deep excavation,the seismic stability of the supporting structures also needs to be checked.The finite element analysis is performed on a soil nailing supported deep excavation.The axial stress within the soil nails under the seismic loading are studied.The results indicate that the seismic load controls the soil nail design under the designated earthquake magnitude.更多还原
