+86 15898932201Seepage Monitoring is used for continuously measuring reservoir seepage flow and seepage pressure data. Combined with dam deformation monitoring, it assesses the effectiveness and stability of dam seepage control, providing critical data support and intelligent early warning for engineering safety operation and risk management.
Seepage Monitoring is a professional monitoring system specifically designed for the safe operation of water conservancy projects. Its core function is to continuously and accurately quantify the seepage state of the dam and its foundation. By collecting and analyzing key parameter data such as seepage flow and seepage pressure, it directly serves dam safety assessment and risk management, and is an indispensable technical means to ensure the long-term structural safety of the dam.
The main functions of this system are reflected in several aspects. The primary function is to measure the seepage flow data of the reservoir. By deploying measuring weirs, flow meters, and other devices, the system can accurately measure the total seepage water volume through the dam body, dam foundation, and both banks, which is the most direct macroscopic indicator for judging whether the dam's anti-seepage system is working properly. Secondly, the system is responsible for monitoring changes in the seepage field. By embedding a network of piezometers in key parts of the dam interior, dam foundation, and slopes, the system can measure the pore water pressure or uplift pressure at each measurement point in real time, thereby depicting the seepage pressure distribution map of the entire dam area. This helps to analyze seepage paths, evaluate the effectiveness of anti-seepage facilities (such as cut-off walls and drainage systems), and calculate the dam's seepage stability.
An important development trend of modern Seepage Monitoring is the integrated integration with dam deformation monitoring. Seepage pressure and dam deformation data such as displacement and settlement are closely related in physical mechanisms. By synchronously collecting and comprehensively analyzing seepage monitoring data with deformation monitoring data obtained from GNSS, surveying robots, and hydrostatic leveling instruments, the system can more accurately reveal the working behavior of the dam, determine whether abnormal seepage has caused structural deformation, or whether structural defects have led to abnormal seepage. This multi-source data fusion analysis significantly improves the accuracy and reliability of the overall safety assessment of the dam.
In terms of practical value in safety management, this system forms the basis for early warning and decision support. By analyzing the trends of long-term monitoring data, a normal behavior pattern of dam seepage can be established. Once the monitoring data shows abnormalities, such as a sudden increase in seepage flow, a significant increase in seepage pressure in a specific area, or a deviation from historical trends, the system can issue a timely warning. This allows managers to detect potential leakage pathways, piping risks, or dam seepage failures in advance, providing an opportunity to take engineering measures before the problems escalate.
Furthermore, continuous seepage monitoring data is an important basis for evaluating the long-term performance of the dam, verifying design assumptions, and guiding reinforcement and repair projects. Through retrospective analysis of historical data, the effectiveness of previous repairs and reinforcements can be assessed, and valuable experience can be accumulated for the design of similar projects in the future. Therefore, Seepage Monitoring is not only a real-time monitoring tool, but also a data foundation that runs throughout the entire life cycle safety management of the dam, providing scientific and intelligent assurance for the safe and efficient operation of the project.
