Decoding Pore Water Pressure with Precision Gauges

Pore water pressure gauges are indispensable and important instruments in the field of geotechnical engineering, mainly used for accurately measuring the pore water pressure in soil or rock masses.

Its working principle is based on the pressure - sensing mechanism. When the pore water in the soil or rock mass exerts pressure on the sensing element of the pressure gauge, the sensing element will generate changes in electrical signals or mechanical signals. Through conversion, the specific value of the pore water pressure can be obtained. Relying on this principle, the pore water pressure gauge can transform the pore water pressure, which is difficult to measure directly, into intuitive readable data.

In soft soil foundation treatment projects, by monitoring the dissipation of pore water pressure, the construction party can reasonably plan the loading rate and effectively prevent the instability of the foundation. In water conservancy projects such as dams and dikes, it plays a crucial role in ensuring safety. Through real - time monitoring of the pore water pressure inside the dam body, once the numerical value shows abnormal fluctuations, it can be detected in a timely manner. This may indicate potential safety hazards such as dam leakage and landslides, providing important basis for the safety assessment of the project.

With the data provided by the pore water pressure gauge, engineers can accurately judge the consolidation state and strength changes of the soil, and then flexibly adjust the construction plan. For example, they can add drainage measures in a timely manner and reasonably change the construction sequence, laying a solid foundation for the smooth progress and safety guarantee of the project.
