The invention discloses an intelligent monitoring pile component, an intelligent monitoring network system and an intelligent monitoring method for pipeline landslides. The intelligent monitoring pilecomponent for pipeline landslides comprises a mother pile and one or more than one son pile which are in communication connection with each other; components such as a communication device, a data acquisition instrument and a power supply device are fixed on a mother pile mounting column, and necessary circuit connection and communication connection are needed among the components; a son pile mounting column is a hollow piece, a communication device, a data acquisition instrument, an angle sensor, a displacement sensor and the like are fixed on the outer wall of the upper section, and necessary circuit connection and communication connection are needed among all the components. The intelligent monitoring component and the monitoring network are high in monitoring refinement degree and data availability, and obtained data has distributed monitoring network data characteristics. The intelligent monitoring network system for pipeline landslides comprises an upper computer and at least one group of intelligent monitoring pile components for pipeline landslides, wherein the mother pile is in communication connection with the upper computer. According to the monitoring method, a data assimilation platform is utilized for processing and arranging monitoring data, a data processing method of two-step assimilation and classification labels is adopted, two-dimensional monitoring data isconverted into a monitoring slope body four-dimensional database, the geological change characteristics of a slope surface are displayed more scientifically and comprehensively, and more decision information for disaster monitoring and prevention is provided.
