Отсчеты снимают на пьезометрическом щите 6 по уровню жидкости, который устанавливаетс  в пьезометрах после изменени  сечени  трубок е зависимости от пол  напр жени  в загружаемой модели. Устройство может быть использовано при проведении сопоставимых испытаний грунтовых моделей, например, при различных вариантах нагрузки, при оценке эффективности различных способов укреплени , при выборе оптимальной конструкции сооружени  и т. п. Предлагаемое устройство позвол ет снизить стоимость и трудозатраты на проведение эксперимента и повысить точность исследований по сравнению с известными устройствами . Формула изобретени  Устройство дл  исследовани  «апр женного состо ни  модели грунтового массива, включающее грунтовой лоток, пьезометрический щит со стекл нными трубками, приспособлени  дл  передачи нагрузки и измерени  напр жений, отличающеес  тем, что, с целью повышени  точности исследований, приспособление дл  измерени  напр жений выполнено в виде раст нутых на всю длину лотка эластичных, заполненных жидкостью трубок, одни концы которых заглушены, а другие соединены с вертикально расположенными стекл нными трубками :пьезометрического щита.

The load is transferred to the model by the head:. The readings are taken on a piezometric shield 6 according to the level of the liquid, which is installed in the piezometers after changing the cross section of the tubes and depending on the voltage in the loaded model. The device can be used when conducting comparable tests of soil models, for example, with different load options, when evaluating the effectiveness of various methods of strengthening, choosing the optimal structure for a structure, etc. compared to known devices. Apparatus of the Investigation Device for the "arcing state of a soil mass model, including an earth tray, a piezometric shield with glass tubes, devices for transferring loads and measuring stresses, characterized in that, in order to increase the accuracy of research made in the form of stretched over the entire length of the tray elastic, fluid-filled tubes, one ends of which are plugged, while others are connected to vertically arranged glass tubes: piezomet nical shield.
