Одно из перспективных направлений – определение длины свай акустическими методами. Эти методы основаны на возбуждении и регистрации упругих волн на поверхности сваи. Ограничением акустических методов является то, что скорость возбуждаемых упругих волн в теле сваи предполагается заранее известной. Опыт исследований показывает, что на практике применение этого условия может приводить к значительной погрешности. Особенно это актуально для буронабивных свай, где скорость распространения упругих волн определяется множеством раз- личных факторов. В рамках конкретного примера показана возможность повышения точности измерения скорости акустических волн в буронабивных сваях. Использование схемы двух каналов измерения, построенной на вводе установленного расстояния между приемными устройствами, позволило повысить точность измерения до 5 %.</p></abstract><trans-abstract xml:lang="en"><p>Non-destructive testing of structures is an effective way to determine their required parameters. One of the promising directions is the acoustic measurement of the pile length using two channels. This method is based on the excitation and registration of elastic waves on the pile surface. A limitation of acoustic methods is that the speed of the elastic waves in the pile is assumed to be known in advance. Research results show that the practical application of this condition can lead to a significant error. This is especially true for bored piles, where the speed of the elastic wave propagation is determined by many different factors. This paper proposes to increase the measurement accuracy of the acoustic wave speed in the bored pile. The use of two measurement channels, which implies the introduction of the specified distance between the receiving devices, made it possible to increase the measurement accuracy up to 5 %.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>акустические методы определения длины свай</kwd><kwd>буронабивные сваи</kwd><kwd>скорость распространения акустических волн в свае</kwd><kwd>поверхностный метод определения длины свай</kwd></kwd-group><kwd-group xml:lang="en"><kwd>acoustic method</kwd><kwd>bored pile</kwd><kwd>acoustic wave speed</kwd><kwd>surface method</kwd><kwd>pile length</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Капустин В.В.
