Description
гистрируют. Гибкую стальную ленту вдоль всей длины модели равномернонагружают .пригрузкой 5, например эластичным резиновым баллоном, заполненным сжатым воздухом. Давление в баллоне равно весу недостающего столба пород. Гибкий промежуточный .элемент 4 прогибаетс над зоной пониженных напр жений и перераспредел ет , воспринимаемое равномерное давление пригрузки, передава его на поверхность модели неравномерно пониженное - на подработанную зону, а повышенное - на неподработанные части модели вблизи зоны оседани массива под вли нием выработки. По мере перемещени подработанной части модели зоны повышенных и пониженных напр жений автоматически перемещаютс в соответствии с изменением параметров обрушенной зоны модели. Если породы под лентой не опускаютс , т.е. выработка не оказывает вли ни на горизонт приложени нагрузки то давление на модели будет передаватьс равномерно. Способ применим как в зоне вли ни выработок, так и вне нее.gistriruyut. Flexible steel tape along the entire length of the model is uniformly loaded with load 5, for example, an elastic rubber balloon filled with compressed air. The pressure in the cylinder is equal to the weight of the missing column of rocks. The flexible intermediate element 4 bends over the zone of lowered stresses and redistributes the perceived uniform pressure of the load, transferring it to the model surface unevenly lowered to the undermined area, and increased to the underworked parts of the model near the subsidence zone of the array under the influence of output. As the underworked part of the model moves, the overvoltage and undervoltage zones automatically move in accordance with the change in the parameters of the collapsed zone of the model. If the rocks under the belt do not fall, i.e. output does not affect the load application horizon then pressure will be transmitted to the models evenly. The method is applicable both in the zone of influence of the workings and outside it.
Данный способ позвол ет получать более достоверные результаты и воспроизводить неравномерное поле напр жений в материале модели горного массива.This method allows to obtain more reliable results and reproduce the uneven stress field in the material of the rock mass model.
