Rock mass internal settlement monitoring system and monitoring method
The invention relates to a rock mass internal settlement monitoring system and monitoring method, and relates to the field of geotechnical engineering deformation monitoring, and the rock mass internal settlement monitoring system comprises a settlement monitoring system and a monitor system. The settlement monitoring system comprises a hollow monitoring pipe with two open ends; the auxiliary guide head is connected with the monitoring pipe; the monitoring pipe is sleeved with the monitoring mark; and the monitor system can be correspondingly and movably adjusted along the hollow inner wall of the monitoring pipe. The monitoring mark is buried in the slurry filled in the drill hole, the slurry is anchored with the hole wall of the drill hole, and the monitoring mark and the rock stratum are driven to synchronously move and deform, so that the range limitation of a traditional mounting base or a limiting ring is eliminated, the influence of hole wall block stone falling on the position of the monitoring mark is avoided, and the precision of rock stratum settlement monitoring can be further improved. For monitoring marks of different specifications, the magnetic intensities generated by the settlement monitor are different, and the monitoring marks at different positions are distinguished according to the difference of the magnetic intensity amplitudes, so that the settlement information of the rock stratum can still be accurately monitored under the condition that part of the monitoring marks are invalid.
本发明涉及一种岩体内部沉降监测系统以及监测方法，涉及岩土工程变形监测领域，包括沉降监测系统、监测仪系统。沉降监测系统包括中空且两端开放的监测管；与监测管相连的辅助导头；套设于监测管外监测标；监测仪系统可沿监测管的中空内壁进行相应的活动调节。本发明将监测标埋设于钻孔内充填的浆液内，浆液与钻孔孔壁锚固，并带动监测标与岩层同步移动变形，消除了传统安装基座或限位环的量程限制，避免了孔壁块石脱落对监测标位置的影响，能够进一步提高岩层沉降监测的精度。对于不同规格的监测标，沉降监测仪所产生的磁强度有所差异，根据磁强度幅值的差异辨别不同位置处的监测标，保证了部分监测标失效情况下，仍能够精准监测岩层的沉降信息。
