Abstract
An experimental setup for measuring the vacuum degree and pore pressure at a point of soil mass in vacuum consolidated state, including a connecting tube, the connecting tube includes an upper water storage tube, a middle tube, the middle tube is loaded with an upper experimental soil mass, the lower tube is loaded with a lower experimental soil mass, a water storage chamber is connected to a pumping mechanism, an intermediate inner chamber is connected to a negative pressure vacuum gauge, the inlet conduit is connected to a negative pressure vacuum gauge. Additionally, the present invention provides a test operation method. The device measures the vacuum degree of upper part of experimental soil mass by observing the reading in the negative pressure vacuum gauge.
