摘　　要：以某风电场风机基础附近滑坡治理及基础纠偏为例,利用MIDASGTS软件建立计算模型,通过对滑坡加固前后的分析计算提出综合利用钻孔灌注桩排桩支护及钻孔灌注桩排桩+预应力锚索支护的滑坡加固方法,采用上设冠梁的排桩作为支挡结构,且距风机基础较远的支护桩冠梁上用预应力锚索拉锚。采用锚杆静压桩对风机基础纠偏,从而达到提高地基承载力和控制沉降的目的。本文方法可在滑坡引起的结构变形加固设计中借鉴与应用。This study investigates a landslide mitigation and foundation rectification project adjacent to a wind turbine foundation within a wind farm.A computational model is developed using MIDAS GTS software to analyze the mechanical behavior of the foundation and surrounding soil before and after landslide reinforcement.A combined reinforcement method is proposed,incorporating a row of bored piles integrated with prestressed anchor rods.The design includes a capping beam atop the pile row as the retaining structure,and prestressed anchor cables are applied to the capping beams of the piles located at ends,farther from the turbine foundation.Foundation rectification is achieved using pressed piles by anchor rods,aiming to enhance the foundation bearing capacity and control settlement.The proposed method provides a valuable reference for foundation rectification design in structures affected by landslides.
