Abstract

The invention, which relates to the technical field of deformation monitoring, discloses a steel truss deformation monitoring and measuring method. The method is characterized by comprising specific operation steps: S1, carrying out steel truss mounting and welding successively in a longitudinal sequence of 1, 2, 3, 4, 5, 6, 7 and 8 and in a horizontal sequence of A, B, C, D, E, F, G and H. According to the disclosed method, two-sided pipe trusses are simultaneously erected and two pipe trusses are welded; each small ring is provided with a sensor to carry out annular monitoring for seven days, next-link hoisting is carried out again and then monitoring is carried out for seven days; after deformation stabilization every seven days, a next annular point position is adjusted and adjustmentis carried out for each annular deformation value; after requirements are met, an adjustment value is allocated to a transfer point and average allocation is performed in a next link; and recursion is performed ring by ring. Therefore, the error closing in the middle of the pipe truss can be realized; and the error is minimized.

Description

technical field [0001] The invention relates to the technical field of deformation monitoring, in particular to a method for monitoring and measuring steel truss deformation. Background technique [0002] In the current measurement field, the deformation observation is caused by temperature, force, load and other reasons. In the monitoring process, from the initial observation with theodolite and level instrument to the application of total station, it is now super station instrument and GPS The comprehensive application of surveying and mapping instruments has developed very fast and the measurement efficiency is also very high. However, the manpower and periodicity in the process of use are long, and the cost of economic investment is relatively large. At present, the most monitoring and measurement methods are mostly adopting a monitoring system composed of various sensors and internal hardware and software. Only relevant devices need to be installed. At the measuring po...
