Construction and application of an online health assessment and restoration platform for expansive soil bank slopes
Developing a full chain technological platform for online health assessment and restoration of expansive soil slopes is helpful in addressing the global issue of controlling expansive soils.In this paper,a mathematical model is constructed,and an online evaluation technology of real-time acquisition data,and the three-level data fusion technology of pixel level,feature level,and decision level are developed.It proposes a dynamic evaluation and early warning algorithm for the health of expansive soil bank slopes,achieving real-time evaluation of the"health","sub health",and"hidden dangers"status and"unhealthy"early warning.It also develops"external isolation and internal drainage"repair and reinforcement measures,and a full chain technology platform have built for the prevention and control of expansive soil bank slopes,from information collection and integration to health dynamic assessment and warning,and then to repair and reinforcement,which has improved the level of prevention and control of expansive soil bank slopes.Using the Songgang Wharf slope at the head of the South to North Water Diversion Canal as the experimental carrier,the results show that the data collected by the platform is complete and well integrated.2203 sets of online evaluation and warning data are consistent with the actual situa-tion,and the algorithm is feasible.The repair and reinforcement measures have significantly reduced soil moisture and seepage pressure,which has promotional value.
