摘要： 为探究黄土地区浅基础建筑纠倾加固的新方法,以兰州市某发生不均匀沉降的2层办公楼为研究对象,分析沉降成因后,创新提出砖基础两侧新增倒L型梁、柱下独立基础对角线顶升的新型纠倾结构及限位迭代顶升方法.经抗弯、抗剪、抗冲切承载力验算确定方案后实施.监测显示原建筑西南侧Q1、Q2和Z1处相对沉降量较大,其中Q1、Z1处累计沉降超40 mm,局部倾斜率0.7%;纠倾后Q1、Z1顶升量均为29 mm,倾斜率降至0.17%,满足规范安全要求,且施工周期短、工艺简单、过程稳定.

Abstract: In order to explore a new tilting correcting method of shallow foundation buildingin loess areas, a 2-story office building with uneven settlement in Lanzhou City was taken as the research object. After analyzing the causes of settlement, a new type of correction structure was proposed, consisting of inverted L-shaped beams added on both sides of the brick foundation and independent foundation diagonal lifting under the column, combined with a limit iteration lifting method. After verifying the bending, shear, and impact shear bearing capacities, the proposed scheme was implemented. Monitoring results show that the relative settlement at Q1, Q2, and Z1 on the southwest side of the original building is relatively large, with a cumulative settlement of over 40mm and a local tilt rate of 0.7% at Q1 and Z1. After correction, the lifting amount of Q1 and Z1 are both 29 mm, reducing the tilt ratio to 0.17%, which meets the safety requirements of the specifications. The construction process was characterized by a short duration, simple procedures, and stable execution.

Key words: shallow foundation, tilting structure, inverted L-beam, tilting structure under column, limit iterative jacking, tilting effect
