成测量技术在基坑变形监测中的应用——以芜湖火车站基坑为例

Application of formation measurement technology in foundation pit deformation monitoring——take the foundation pit of wuhu railway station as an example

在自然界变形是广泛存在的现象。在各类载荷作用力之下,在空间和时间域中各变形体的形状、大小以及位置发生改变。变形的范围可大可小,大到地球板块运动和地极移动等涉及整个地球的变形,小到对于工程建筑而言的沉降、倾斜、滑坡体滑动等地域性变形,总之,变形几乎无处不在。所谓变形监测的概念就是说应用一些测量方面的仪器和方法监测变形体,以免造成由变形所带来的有关灾害,避免损失。

deformation is a widespread phenomenon in nature,that is,under various loading forces,the shape,size and position of each deformation body in the space and time domain will change.The scope of deformation can be large or small,ranging from the plate movement and pole movement of the earth,which involve the deformation of the whole earth,to the subsidence,tilting,sliding and other regional deformation of engineering buildings.In a word,deformation is almost everywhere.The so-called concept of deformation monitoring is to apply some measuring instruments and methods to monitor deformation,so as to avoid the related disasters caused by deformation.If such losses can be avoided,it is the best,and if they cannot be avoided,we should try our best to reduce it.
