Abstract
The purpose of installing tools in a tunnel and its readings with a convergence meter, which is one hundredth of a millimeter precision, is to increase the accuracy and sensitivity of the work. Therefore, identifying the factors affecting the results of instrumental research is one of the most important factors in health and increasing the accuracy and reliability of convergence meter data. In this paper, two important factors, namely, the method of convergence pin installation and the type of working with a convergence meter, which includes one or two operating pressures, have been investigated and the results have been analyzed and analyzed in each of the aforementioned cases. They are compared to each other to get an error rate. According to the results of this study, which is done by studying the case of line a of the Qom subway, we investigate which method of installing the pin of convergence is better and show more real results, as well as the difference between single-span and two work pressures what is the convergence meter and what should be done to ensure that the accuracy of the actual data is high.
