The invention proposes a measurement system and method for continuously monitoring tunnel convergence, which are used to solve the problems of complicated operation, low efficiency, and difficulty in ensuring monitoring quality and construction safety of existing tunnel monitoring means. The measurement system includes pulleys, wires, data acquisition modules, data acquisition stations and storage modules. The pulleys are fixed on the monitoring points of the tunnel, and the monitoring points form an open polygon. One end of the wire is fixed on one end of the open polygon, and the wires are arranged at each monitoring point in turn. On the pulley, the end of the wire is fixed with a counterweight that keeps the wire close; the data acquisition module set on the monitoring point is used to detect the distance and angle of each section of the open polygon. The data acquisition module and the data acquisition station The data acquisition station is connected with the storage module, and the storage module is connected with the upper computer; according to the measurement system, the measurement method for determining the convergence of the tunnel can be realized.
Description
technical field [0001] The invention relates to the technical field of tunnel monitoring, in particular to a measuring system and method for continuously monitoring tunnel convergence. Background technique [0002] With the rapid development of my country's infrastructure construction, the number and scale of tunnel construction are constantly expanding. Tunnels are underground concealed projects with complex underground geological conditions, and there are many potential and unpredictable geological factors. Some tunnels are large in scale and can be several kilometers or tens of kilometers long. They often pass through many different environmental airspaces and time domains. A little carelessness will cause landslides, subsidence, sudden mud gushing, deformation of supporting structures, and personal injury. etc., thereby affecting tunnel security. In order to ensure the safety of tunnel engineering and timely forecast dangerous situations, monitoring and measurement has...
