Abstract
Over time, structures such as slopes and retaining walls are increasingly deteriorating,
resulting in a risk of collapse. Factors such as climate change, human activities, societal
development, rapid growth of cities, increasing population and economy make
geological disasters occur more frequently than usual. Geological hazards of nature,
slope collapse, slope fractures or slope movements have become a problem to be solved
by civil engineering. With the advent of low-cost sensors, optical topographic surveying
and BIM (Building Information Modelling), such risk could be mitigated and, in some
cases, eliminated. The main aim of this research was to use wireless sensors to monitor
slopes that are potentially at risk and to incorporate all the information obtained in BIM
(Building Information Modelling), in order to make a digitalized vision of the structures
in real time. High precision and innovative tools, such as drone flights and slope scanners
were utilized for a detailed analysis of the risk of change in the geohazards including soil
slopes and historic retaining walls. Through the combination of data from sensors with
point clouds generated from drone flights, an early warning system was developed. This
early warning system was clearly able to display when there was surface changes
therefore highlighting the areas of high risk of collapse. This thesis shows how
continuous real-time surveillance of soil slopes and retaining walls can be achieved
clearly and concisely, in a cost-effective manner.
