摘要：

为保证大断面巷（隧）道收敛变形精确测量，研发了便捷式激光测距仪新装置，通过结构设计创新，新装置利用万向球云台替代多轴连接杆，提高了发射接收装置的稳定性和校准能力，最终实现了原位测量；测点布置采用改进的十字型布置方式，增加BE测量路线,形成五测点矩阵ABB′CE；利用小变形原理和三角函数原理推导出了巷道收敛变形计算原理，分别得到了巷道两侧帮相对中轴线的位移量和顶底板的位移量。由于客观因素导致测量数据存在误差，因此针对单次测量和多期测量分别进行误差处理，采用测定值子样平均值来估计单次测量真值，多期测量采用半参数回归分析法消除误差。新型装置在贵州开阳磷矿下属马路坪矿区得到了首次应用，对新开挖大断面巷道表面收敛变形进行长期监测，获得了该矿区深部软岩巷道的基本变形规律。

Abstract:

A highefficient portable laser range finder is developed so as to accurately measure the surface convergence/deformation of tunnel crosssection. The stability and calibrating capacity of the device are improved and the insitu measurement is realized by replacing the multiaxis joint lever by universal joint. The improved cross layout mode is used for measuring points; and BE measuring line is added. The calculation formulas of surface convergence/deformation of tunnel are deduced by small deformation principle and trigonometric function; and the relative displacement of tunnel surface sides to axial line and that of tunnel roof and floor are obtained respectively. Errors objectively exist in measuring; as a result, error processing should be carried out for singlepoint measuring and multiphase measuring. The true value of singlepoint measuring is estimated by average value of repetitive measured subsample data; and that of multiphase measuring is estimated by semiparametric regression method. The abovementioned device has been successfully used in Maluping Mine in Guizhou province for the first time; and the basic deformation rules of deep soft tunnel of the project have been obtained.

Key words: large crosssection tunnel, surface convergence/deformation, portable laser range finder, error processing, insitu measurement, measuring device
