The invention discloses a ground surface settlement monitoring system and method. The system comprises a working base point disposed at a relatively stable foundation position on a ground surface, wherein the ground of the working base point is provided with a benchmark cap head; a plurality of displacement monitoring devices arranged at the corresponding monitoring points, wherein each displacement monitoring device comprises a fixing rod arranged in a stratum in a beating mode, a fixing device being arranged at the top end of the fixing rod, a displacement sensor being fixedly arranged in the fixing device, the measuring end of the displacement sensor being connected with one end of the connecting wire, and the other end of the connecting wire being connected with the benchmark cap head,a housing of the fixing device being provided with a via hole for the connecting wire to penetrate through, the connecting wire being sleeved with a protection pipe, and the protection pipe being buried under the ground surface; and a signal processor used for being connected with the plurality of displacement sensors, wherein the signal processor is connected with a control host.
Description
technical field [0001] The present disclosure generally relates to the technical field of geotechnical engineering surface settlement monitoring, and specifically relates to a surface settlement monitoring system and a monitoring method thereof. Background technique [0002] Surface settlement monitoring is an important part of tunnel construction. Ground settlement should be monitored at a certain period during tunnel construction and later operation, and the data obtained from the monitoring should be calculated and processed to finally obtain the surface settlement. According to the surface settlement Quantitatively guide and handle the construction of the project. The existing conventional surface subsidence monitoring methods include settling plate method, settling water cup method, iron ring layered settling instrument method, section settling instrument method, etc. These monitoring methods are complicated to install, difficult to collect data, and have a large worklo...
