紧邻变电站的高陡自然边坡经过人为作用形成多级高陡坎人工边坡,为了明确变电站的安全性,对人工边坡进行勘察,勘察试验方法主要采用大型原位剪切试验,试验得出关键土层的力学参数,并采用Bishop法分析人工边坡的稳定性,分析结果表明边坡深层位置处于稳定状态,但经过工程地质类比等方法定性分析表明边坡表层形成的高陡坎易发生滑塌,且部分已经发生滑塌,多级的高陡坎长期多次滑塌易引起浅层滑坡的产生,从而影响变电站的安全,因此人工边坡采用板肋式锚杆加坡脚挡墙支护技术的治理措施。
In order to clarify the safety of the substation, the artificial slope is reconnaissance, and the test method of survey mainly adopts the large-scale in situ shear test, and the experiment results show Bishop method is used to analyze the stability of the artificial slope. The analysis results show that the deep slope position is in a stable state. However, the qualitative analysis of engineering geological analogies shows that the high-steep slope formed on the slope surface is easy to occur And some of them have been slipped. The long-term multiple slips of multi-level high-steep slopes can easily cause the occurrence of shallow landslides and thus affect the safety of substations. Therefore, Support technology support measures.
