摘自《西北建筑动态》黄土地区建筑物或构筑物因地基湿陷而引起的事故,采用人工浸水或加压方法矫正效果显著。兰州石油化工机器厂103号烟囱高31.17米(基底起算),由于北端锻热车间的生产用水浸入,造成烟囱地基不均匀湿陷,烟囱向NE8°33′31″倾斜,由甘肃省建工局科研所采用浸水加压法予以矫正。先加固了已严重压裂的下部筒身和基础圈梁,然 Excerpted from the “Dynamics of Northwestern Buildings” in the loess area of ​​buildings or structures due to the foundation caused by the collapse of the accident, the use of manual water immersion or pressure correction effect is significant. The No. 103 chimney of Lanzhou Petrochemical Machinery Factory is 31.17 meters high (based on the basement). Due to the immersion of production water at the northern end of the forging workshop, the foundation of the chimney is unevenly collapsed, and the chimney tilts towards NE8°33′31′′. The construction and construction bureau of Gansu Province The research institute was corrected by the immersed pressurization method. First, the lower shank and the foundation ring beam that had been severely fractured were reinforced.
