      <abstract xml:lang="ru">
        <p>Технологией строительства односводчатых станций Петербургского мет­рополитена предусматривается разрабатывать ядро станции, которое содержит основную часть породы, вынимаемую при строительстве станции, после соору­жения верхнего свода. До последнего времени эта работа выполнялась в ос­новном с помощью отбойных молотков.</p>

        <p>The technology of construction of single-wall stations of the St. Petersburg Metro provides for the development of the station core, which contains the bulk of the rock excavated during the construction of the station, after the construction of the upper vault. Until recently, this work was carried out mainly with the help of jackhammers.</p>
