摘要:
本文阐述了巷道围岩深部及表面位移的测量原理,分析了两种常规测量手段的不足之处,为了提高测量精度、真实度,减少测站的安装,提出了一体化测量巷道围岩深表位移的两用多点位移计,并基于两用多点位移计阐述了测算深部围岩离层、真实位移和深表比的方法,为研究巷道围岩运移规律,合理进行巷道支护设计提供了科学有效的数据支撑。
关键词: 新型多点位移计, 一体化测量, 测算, 深部真实位移
Abstract:
This article illustrates the measuring principle of deep and surface displacements of surrounding rock of roadway, analyses the disadvantages of two kinds of conventional measuring methods,proposes a new combination multi-point displacement meter which can comprehensively measure deep and surface displacement of surrounding rock, improve the measuring precision and validity ,reduce observation station, and based on this new instrument illustrates a method of measuring and calculating the deep surrounding rock separation , real displacement and the ratio of deep and surface displacement, which provides scientifical and valid data for researching the movement rule of surrounding rock and designing roadway support reasonably.
Key words: new combination multi-point displacement meter, comprehensive measurement, measuring and calculating, real deep displacement
