针对复杂穿越工程中岩土体竖向位移监测的问题,开发了一种可用于盾构穿越施工控制的非开挖水平测斜监测技术。阐述了该项监测技术的基本原理与数据计算处理方法;介绍了水平测斜管的埋设过程,包括导向钻进、扩孔护壁、牵引回拖等;在强调了初始值的读取和管口高程修正之后,分别描述了采用人工测量和自动测量两种方法的监测程序;最后,用三个工程实例说明该监测技术在地下穿越工程中具有数据准确灵敏、受外界条件干扰小、监测数据连续等优点,且具有良好的适应性。
In view of the problem of vertical displacement monitoring of rock and soil in complex crossing engineering, a non-excavation horizontal inclinometer monitoring technology that can be used for shield crossing construction control is developed. The basic principle of the monitoring technology and the data calculation and processing method are described. The embedding process of the horizontal inclinometer pipe is introduced, including the guide drilling, reaming protection wall, towing back towing, etc. In emphasizing the reading of the initial value and the nozzle Elevation correction, respectively, described the use of manual measurement and automatic measurement of two methods of monitoring program; Finally, the use of three examples of examples of monitoring technology in the underground crossing with accurate data, interference by external conditions, continuous monitoring data And so on, and has good adaptability.
