Method for monitoring high-precision deformation in real time in tunneling construction, and calculating algorithm

Abstract

The invention relates to a method for monitoring high-precision deformation in real time in tunneling construction, and a calculating algorithm. The method comprises the following implementation steps: A, installing radio frequency pseudo-satellite positioning base stations at an excavated tunnel face and in a tunnel portal space region, and precisely determining base station coordinates; B, installing a wireless positioning data receiving terminal for representing a location identity thereof on each to-be-monitored point, and receiving a RF radio signal emitted by each base station; C, receiving observation data between each terminal and each base station in real time through a software system, calculating high-precision displacement information of the terminal and broadcasting displacement monitoring information to an engineering informatization management platform; D, visualizing real-time displacement deformation and accumulated displacement deformation of each monitoring point; and E, performing risk early-warning by setting a threshold through an early-warning system of the monitoring point displacement deformation, wherein the system can immediately triggers an automatic warning system once the displacement deformation exceeds the threshold, and an operator on duty can immediately adopt a corresponding safety emergency measure to guarantee construction security.

Description

technical field [0001] The invention relates to the technical field of radio frequency pseudo-satellite indoor high-precision positioning, in particular to a method for real-time high-precision deformation monitoring in underground excavation construction. Background technique [0002] With the continuous deepening of my country's economic construction and the continuous adjustment of the economic structure, new requirements are put forward for the construction of transportation infrastructure. In recent years, the vigorous development of highways, bridges, railways, tunnels and other engineering constructions has become an important means to relieve traffic pressure and shorten traffic time-consuming, especially tunnel traffic, which has effectively alleviated traffic congestion, shortened construction mileage, and reduced construction costs. cost, and various tunnel safety accidents that follow frequently occur. The situation of safe production in tunnel and subway constr...

Problems solved by technology

However, these measures are based on experience and control of the construction process, and there is still a lack of effective, high-precision, real-time displacement monitoring data, so that the construction accuracy and process and effective preventive measures that can be flexibly adjusted according to the actual safety hazards, resulting in major Safety construction accidents still occur from time to time, such as: collapse in the cave, large deformation, etc.
