为了确定某滑坡的治理方案，在分析工程地质条件的基础上，采用数值模拟方法对比分析了抗滑桩、预应力锚索框架梁、抗滑桩预应力锚索框架联合支护3种方案，结果表明，在滑体中上部采用预应力锚索框架梁支护，在滑体中下部采用抗滑桩支护的抗滑桩预应力锚索框架联合支护方案为最优方案，抗滑桩与锚索框架梁的合理距离宜在10 m左右。对最优方案进行优化设计，确定了该滑坡的支护结构形式。施工1a后的边坡变形监测结果符合工程要求，与数值模拟结果也比较吻合，表明该滑坡的优化支护方案是合理的。
為瞭確定某滑坡的治理方案，在分析工程地質條件的基礎上，採用數值模擬方法對比分析瞭抗滑樁、預應力錨索框架樑、抗滑樁預應力錨索框架聯閤支護3種方案，結果錶明，在滑體中上部採用預應力錨索框架樑支護，在滑體中下部採用抗滑樁支護的抗滑樁預應力錨索框架聯閤支護方案為最優方案，抗滑樁與錨索框架樑的閤理距離宜在10 m左右。對最優方案進行優化設計，確定瞭該滑坡的支護結構形式。施工1a後的邊坡變形鑑測結果符閤工程要求，與數值模擬結果也比較吻閤，錶明該滑坡的優化支護方案是閤理的。

In order to determine the optimal programs for control of a landslide, three programs, including anti-slide piles, prestressed anchor-cable frame beam, and anti-slide piles combined with prestressed anchor-cable frame, were analyzed and compared based on investigations of the engineering geological conditions and numerical simulation. The results show that the optimal programs are the second program for the upper-middle part of the landslide body and the third program for the lower-middle part of the landslide body, and the suitable distance between the anti-slide pile and the anchor-cable frame beam should be about 10 m. The supporting structures of the landslide for the optimal programs were determined through optimal design. The monitoring results after one year of construction show that the slope deformation meet the engineering requirements, and the numerical simulation results are in good agreement with the monitoring ones, indicating that this optimal program for landslide supporting is reasonable.
