Development Survey of a Monitoring and Early Warning System for Banks and Dams of Expansive Soil

Expansive soil is a kind of soil with special properties, widely distributed, difficult treatment technology, and affecting the engineering safety of banks and dams. It is particularly necessary to summarize the development status and trend of the monitoring and warning system of banks and dams for expansive soil based on the characteristics of expansion soil. Based on extensive literatures, the progress of the hardware and software were systematically analyzed for the monitoring and warning system of banks and dams for expansive soil. Specially, the hardware mainly includes: sensors, data acquisition, data transmission, and postprocessing platform and so on; The software mainly includes: multi-sensor integration, data sharing, post-processing, human-computer interface, and route planning of unmanned aerial vehicle and so on. Accordingly, the research directions of the hardware and software of monitoring and early warning system are put forward, and the results will be used for references in the development of monitoring and warning system, engineering construction, engineering management, and emergency management and so on for banks and dams of expansive soil.
