The invention discloses a multi-information monitoring device of an arching method, which can realize four monitoring of settlement, inclination, vertical displacement of internal rock mass and convergence of arch waist for a monitoring point at the arch foot of the station during the construction of the arching method. Simultaneous monitoring of the project realizes the integration of multiple monitoring information and reduces the number of monitoring points. At the same time, based on the multivariate information of the subsidence, inclination, vertical displacement of the internal rock mass and the convergence of the arch waist monitored by the device, and there is a certain nonlinear relationship, a time series prediction model is established based on the monitoring data. The bird algorithm optimizes the key input parameters of the time series prediction model, and further improves the prediction accuracy of the monitoring data on the basis of realizing the prediction through the time series prediction model.
Description
technical field [0001] The invention relates to the technical field of construction monitoring of subway stations, in particular to a multi-information monitoring device of an arch cover method. Background technique [0002] In the construction process of the subway station arch cover method, the change of the rock mass at the arch foot of the buckle arch at the top of the station is the focus of the construction process. Whether the buckle arch foot is stable or not reflects whether the on-site construction is in a safe state. During the construction of the station arching method, by monitoring the settlement value, inclination value, the convergence value of the arch foot and the vertical displacement value of the rock mass at the foot of the arch in real time, the safety state of the construction environment on site can be effectively determined to ensure Safe construction on site. However, in the construction process, there is a certain lag in manual monitoring, which c...
