在线光电远程位移检测技术在沉井施工监测中的应用初探

A TENTATIVE STUDY ON THE APPLICATION OF THE ONLINE DISPLACEMENT MEASUREMENT TECHNOLOGY OF LONG DISTANCE OBJECTS BASED ON OPTICS AND ELECTRONICS IN MONITORING SYSTEM OF OPENED CAISSON CONSTRUCTION

沉井施工中 ,防止不均匀下沉、突沉、控制终沉是施工成功的关键 ,为此在线的实时施工监控很重要 ,在量测沉井的位移时 ,传统的方法已不能满足项目的大型化和施工自动化的要求 ,为此本文提出一种基于光电远程位移检测技术的沉井位移监测方法 ,它的实时、高精度和与计算机接口的信息处理快速性 。

It is important to prevent uneven and sudden sinking and to control the depth of the sinking during the construction period of opened caisson. Yet the traditional methods for displacement measurement can no longer fulfill the requirements of the larger and automaticaly constructed projects. In this paper an online displacement measurement technology of long distance objects based on optics and electronics is presented. It is valuable for features of online measurement, high precision and high transacting speed with the computer. \[
