利用 Midas/GTS 数值模拟软件选取最不利滑坡剖面进行二维建模，应用强度折减理论分析滑坡在天然状态下的稳定性，得出滑坡的最大剪应变、最大剪应力、滑动面及安全系数。通过 Midas/GTS 中锚建模助手建立锚杆并施加预应力对滑体进行加固，分析加固后滑坡稳定性。结果表明，预应力锚杆大大提高了滑坡体的安全系数。
利用 Midas/GTS 數值模擬軟件選取最不利滑坡剖麵進行二維建模，應用彊度摺減理論分析滑坡在天然狀態下的穩定性，得齣滑坡的最大剪應變、最大剪應力、滑動麵及安全繫數。通過 Midas/GTS 中錨建模助手建立錨桿併施加預應力對滑體進行加固，分析加固後滑坡穩定性。結果錶明，預應力錨桿大大提高瞭滑坡體的安全繫數。

Using the Midas/GTS numerical simulation software to select the most unfavorable two-dimensional landslide profile for modeling, with strength reduction theory analyzed landslide stability under natural state, calculated landslide of maximum shear strain and maximum shear stress, sliding surface and safety factors. Then using Midas/GTS anchor modeling assistant established the sliding body and prestressed anchor reinforcement, analyzed landslide stability after reinforcement. The results showed that prestressed anchor rod greatly improved the safety factor of landslide.
