［摘要］目前纠倾技术主要依靠过去经验来指导工程实践，以往的纠倾对象多为多层和低层建筑，高层建筑纠倾尚未形成系统的理论和设计施工体系。采用ABAQUS软件模拟某高层基础少倾侧开挖卸荷沟纠倾技术实施情况，得出卸荷沟最优深度为20～25m，与建筑最优距离为1m。建议卸荷沟开挖厚度为0-2m，与建筑边缘距离为1m，开挖宽度为20m，开挖深度为15m。

Abstract:At present, the rectification technology mainly relies on the past experience to guide the engineering practice. In the past, the object of rectification is mostly multi-storey and low-rise buildings, and there is no systematic theory and design and construction system for high-rise buildings. ABAQUS finite element software was used to simulate the implementation of  excavation unloading ditch method for rectification on  less inclined side of high-rise building foundation to find the optimal depth of the unloading ditch is 20～25m and the optimum distance from building is 1m. It is suggested that the excavation thickness is 0-2m, the excavation distance is 1m, the excavation width is 20m and the excavation depth is 15m.

Keywords:high-rise building; rectification research; finite element simulation; unloading ditch method
