Therefore, the research on the pore pressure has important significance and necessity.
The international relatively advanced hole pressure measurement technology has a pressure difference type optical fiber sensor measurement mode, and can be used for carrying out detailed and effective monitoring on the position of a measurement point. However, the technical means can only perform single-point measurement at a certain moment, so that the soil mass in the area cannot be subjected to all-around data measurement and result analysis. However, in the existing method for solving the problems, a multi-time plugging and unplugging method is usually adopted, so that the sensing probe is positioned at different positions to measure the pore pressure at different positions, but in the multi-time plugging and unplugging process, the soil body is disturbed, and a certain access exists between the measurement result and the actual data result.
In addition, the monitoring area of the existing geological and physical property monitoring probe rod is limited, and the three-dimensional monitoring of the measuring area cannot be realized at a certain moment, so that the subsequent analysis has no continuous comprehensiveness, and the pore pressure distribution and properties of the area cannot be integrally researched.
