摘要

结合传统收敛测量和全站仪测量两种测量方法的优势，提出了一种新的收敛测量方法。传统收敛测量方法存在着操作要求高，施工干扰多，不易长期监测等缺点；全站仪测量方法由于采用间接测量策略，测点间的距离需要进行解算，施测精度较低。新方法延用了全站仪测量方法所采用的激光测距技术，同时也延用了传统收敛测量方法采用的直接测量距离策略。借助于目前市场上成熟的激光测距产品，研制和加工了新方法所需的测量装置。它由5个部分组成，依次为激光测距仪、测距仪底座、测量基点连杆、连接套筒、测量基座。按照一定的实施步骤，在程潮铁矿采空区的地面隧道进行了测量精度在现场工程环境下的试验评估。试验结果表明，新方法的成本低廉、操作简捷、稳定性好，施测精度可达到0.7 mm，有利于收敛监测在地下工程建设过程中的普及应用。

Abstract

A new laser convergence monitoring method is proposed

combining with the advantages of the current two measurement methods

i.e. traditional convergence measurement and total station measurement. For the traditional convergence measurement method and total station measurement method

both have some disadvantages

such as high operation requirements

the construction disturbance and difficult to long-term monitoring

etc. risen from by the former

and lower accuracy raised by the latter. Laser ranging technology used by total station measurement has been adopted

at the same time direct-measure strategy used by traditional convergence measurement also has been followed. By virtue of the existing laser ranging products

the measuring apparatus required by the new method has been designed and processed out. The apparatus consists of five parts which are laser rangefinder

rangefinder base

connecting rod

connecting sleeve and measuring base. According to the specific implementation steps

the measurement precision in on-site engineering environment has been tested and estimated in the tunnel of Chengchao Iron. The test results show that the new method is low-cost

simple operation

good stability

and the measurement precision can reach 0.7 mm. Therefore it is useful for universal application of convergence monitoring to the process of construction of underground engineering.
