| Abstract: | Taking two-way inclined deformation of a low-level residential building in Lanzhou,which was caused by uneven settlement of its foundation,as the engineering background,the origin of its inclination was analyzed.Aimed at the features of low-stress foundation and weak rigidity of building,the inherent characteristics of collapsible loess was investigated,the spacing,depth and other parameters of holing were determined with plastic theory,and the technical proposal for forced settlement rectification was desi... |
