Abstract | FAST台址巨石混合体的开挖稳定性对工程的建设和安全运营具有重要的意义。本文选取典型剖面,对FAST台址巨石混合体边坡在开挖后可能发生的坡体内部深层滑动和表层块体失稳两种破坏模式进行研究。结果表明:巨石混合体边坡沿最危险滑动面滑动的稳定系数约为2.8,不会发生坡体内部滑动。开挖后坡体上部较陡部位的表层块体由于失去支撑而发生失稳,再带动后方的块体运动。块体运动过程中重新堆积、咬合,体现出一定的自稳性。研究结果可为FAST台址巨石混合体及类似地质体的稳定性评价提供参考。 |
Other Abstract | The excavation stability of large rock mixture slope in FAST location is important to the project.This paper studies the possible two damage models that are deep layer sliding in the slope and the rock block failure in the surface layer,by choosing typical section.The results show that the stability factor of the most dangerous slip surface is about 2.8.So the large rock mixture slope will not slide inside.The rock block in the surface layer of the upper part of the slope is easier to destabilizing because ... |
