摘要
目前监测上海市地面沉降的观测标按照标杆导正方式进行划分,主要有两种结构即钢丝绳导正式和导轮扶正式。钢丝绳导正式标的稳定性一般较差。本文仅对钢丝绳导正式标的结构存在的问题,从力学角度进行了分析探讨,并对今后观测标的合理结构提出一些看法。
According to the guide type of the pole, the observation pole now used to monitor the ground settlement in Shanghai has two kinds of structure, i.e. cable guide and guide wheel. Gene. rally, the stability of the pole with cable guide is poor. This paper analyses, from the viewpoint of mechanics, the existing problems in the structure of the pole of cable guide and makes suggestions to the rational structure of the obsvation pole in the future.
