［摘要］結合南京某復雜山地建筑邊坡加固治理工程，闡述山地建筑邊坡多排抗滑樁加固設計方法。首先采用極限平衡法分析確定山地建筑邊坡潛在滑動模式及潛在滑面分布形式，并通過反分析確定滑帶土力學參數。然后采用滑坡推力法、有限元數值模擬綜合確定多排抗滑樁受力特性，為編制山地建筑邊坡加固治理方案提供依據，最后采用有限元強度折減法、極限平衡法復核加固后邊坡穩(wěn)定性，確保治理方案安全合理。工程實踐表明，采用多排抗滑樁對山地建筑邊坡不同滑坡模式的潛在滑坡均有較好的防治效果，適用于潛在滑動模式復雜、潛在滑面影響范圍廣且滑面較深的邊坡加固治理。

Abstract: Combined with a slope reinforcement and treatment project of a complex mountain building in Nanjing, the reinforcement design method of multi-row anti-slide piles for slope of mountain building was described. Firstly, limit equilibrium method was used to analyze and determine the potential sliding mode and distribution form of potential sliding surface of mountain building slope, and the mechanical parameters of sliding zone soil were determined by back analysis. Then, the landslide thrust method and finite element numerical simulation were used to comprehensively determine the mechanical characteristics of multi-row anti-slide piles, which provided the basis for the preparation of slope reinforcement and treatment plan of mountain buildings. Finally, the finite element strength reduction method and limit equilibrium method were used to check the stability of the slope after reinforcement to ensure the safety and rationality of treatment plan. The engineering practice shows that the use of multi-row anti-slide piles has good prevention and control effect on the potential landslide of different landslide modes of mountain building slope, and it is suitable for the reinforcement and treatment of slopes with complex potential sliding modes, wide influence range of potential sliding surface and deep sliding surface.
