1 引言 建筑物倾斜是软弱地基上一种常见的工程问题,可以在单向(纵向或横向)或者双向(纵横两个方向)发生,当建筑物各部位的倾斜不等量时建筑物会产生挠曲或扭转,并使上部结构产生次应力。当结构构件强度不足时,便产生裂缝,甚至破坏。明显的倾斜会严重影响建筑物的功能,致使门窗难以启闭、物体自行下滑、管道受损、设备仪器失灵等等。当倾斜(尤其是高层建筑和高耸结构的倾斜)较明显地被感
1 INTRODUCTION Building inclination is a common engineering problem on weak foundations. It can occur in one direction (vertical or horizontal) or two directions (horizontal and vertical directions). When the inclination of various parts of the building is not equal, the building will produce Flexes or twists and creates secondary stresses on the superstructure. When the strength of the structural member is insufficient, cracks may occur or even be destroyed. Obvious tilt will seriously affect the function of the building, making doors and windows difficult to open and close, objects falling on their own, damaged pipes, equipment and equipment failure. When tilting (especially the tilt of tall buildings and towering structures) is more clearly felt
