Об оценке точности обратной линейно-угловой засечки при передаче координат на монтажные горизонты при строительстве зданий повышенной этажности

摘要

Рассматривается методика оценки точности обратной линейно-угловой засечки (ОЛУЗ) при строительстве зданий повышенной этажности. Выполнено знаковое моделирование, показавшее, что ограничения на величину угла однократной ОЛУЗ в пределах 30-150° не теряют своей актуальности. Установлено, что эти ограничения не относятся к многократным ОЛУЗ с тремя и более исходными пунктами.%The method of estimating the accuracy of the inverse linear-angular intersection (transliteration -OLUZ) in the construction of high-rise buildings is considered. The technique is based on a single algorithm, encapsulated in determination of the perimeter and the closing quadratic polygon gradients, measured angles and distances of intersections depending on their weights. The sign simulation has shown that the restrictions on the value of the angle of a single OLUZ within 30-150° are of the relevance. It is stated that those restrictions cannot be applied to multiple OLUZ with three or more initial points. The examples of multiple OLUZ show that any value of weight will produce the same result of the accuracy assessment. It is established that the changes in the errors of OLUZ depending on the lengths of its sides are within the accuracy of distance measurement. According to that fact the well-known conclusion that the location of the defined point inside the figure formed by the initial points is the best one is confirmed. It is shown that the increase in the number of initial points to more than three practically does not affect the accuracy of OLUZ.
