Using side-point method for increasing the accuracy of surveying network at monitoring engineering structures

Abstract

Geodetic monitoring buildings and structures is a complex and critical task nowadays, that requires high accuracy of measurements. Various methods are used to obtain it when working on various structures. The author describes the technology of using the side-point method to increase the accuracy of creating a surveying network when monitoring stadiums for the World Cup 2018. It is shown that the application of the aforementioned method together with the well-known one of dead distances measuring with total station does not significantly increase the complexity of the work, but provides high measurement precision even under adverse observation conditions. The features of adjusting such measurements are set out in the article. It is also experimentally established that using the side-points method enables increasing the accuracy of measurements by 1,5–2 times when constructing polygonometric traverses. The article may be useful for at specialists monitoring and geodetic control of structure deformation.
