不规则形状基坑水平位移监测方法研究

通过对一不规则形状基坑水平位移监测实例的介绍,阐述了一种在利用高精度全站仪与特制棱镜条件下的觇牌法与距离测量法相结合的水平位移监测方法,并对其观测精度做了详细分析,结果表明该方法具有精度高、布点简单、易于观测和对场地无特殊要求等优点,在类似基坑水平位移监测中值得借鉴。

STUDY ON THE HORIZONTAL DISPLACEMENT MONITORING METHOD OF THE IRREGULAR SHAPE BUILDING PIT

By presenting an example of the horizontal displacement monitoring to an irregular shape building pit,a kind of horizontal displacement monitoring method was expounded,which was based on the high accuracy total station and the special designed prism,and was an combination of target method and distance measurement.The monitoring accuracy of this method was analyzed in detail and the result indicated that this method had the advantages of having high monitoring accuracy,easy to implant point,easy to measuring,having no special need to the field and so on.It is good for drawing on the horizontal displacement monitoring to the similar building pit.
