technical field [0001] The invention relates to an integrated monitoring system and monitoring method for seepage behavior of water engineering in complex environments, belonging to the field of health monitoring of water engineering. Background technique [0002] Water engineering is a large-scale system engineering with complex structure and variable external loads. Traditional research is mostly based on the development of classical mathematics and mechanics theories. Most of them analyze the safety characteristics of embankment structures from a qualitative and static perspective, ignoring the internal The variability and dynamics of parameters have long-term effects on the engineering structure itself. Seepage damage is one of the most important factors affecting the safety of hydraulic structures.

Problems solved by technology

[0003] For traditional sensing devices, they often have poor anti-electromagnetic interference ability, easy to be affected by humid environment, short service life, single-point single-physical quantity monitoring, too many leads, and extremely prone to drifting of measured values, which affect the monitoring effect. Therefore, it is necessary to develop advanced and practical monitoring technology and equipment. With the continuous improvement of people's safety awareness and monitoring technology, a number of representative methods have been derived: ultrasonic detection method, acoustic method, magnetic particle method, detection method, etc. Ground radar, tracer method and other technologies, but this kind of new method has little effect on the seepage monitoring of water projects. It is necessary to improve the old technology and explore new technologies. Distributed optical fiber monitoring technology is currently a relatively mature monitoring method , has the advantages of strong anti-electromagnetic interference ability, not easily affected by the external environment, long service life, distributed multi-parameter monitoring, not easy to drift in measured values, low price, and convenient layout. Therefore, based on sensing optical fiber technology in water The application research of engineering is of great significance, but the distributed optical fiber monitoring technology is not practical in the field of water engineering seepage monitoring, and it cannot be directly applied to the field of water engineering seepage monitoring. It needs to be improved and innovated, proposed and constructed A truly practical sensing system for seepage monitoring based on distributed optical fiber technology
