Highway Cross Slope Measurement Using Airborne And Mobile Lidar, Alireza Shams Esfandabadi
All Dissertations
Ensuring adequate pavement cross slope on highways can improve driver safety by reducing the potential for water sheeting and ponding. Collecting cross slope data is typically only based on small sample because efficient technology and means to collect accurate cross slope data has been evasive. The advent of Light Detection and Ranging (LiDAR) scanning technology has proven to be a valuable tool in the creation of 3D terrain models. Combined with other technologies such as Global Positioning Systems (GPS) and Inertial Measurement Unit devices (IMU) it is now possible to collect accurate 3D coordinate data in the form of a …
Coupled Hydrological-Geotechnical Model For Determinine Bearing Capacity And Elastic Settlement Of Foundations, Vahidreza Mahmoudabadi Arani
Coupled Hydrological-Geotechnical Model For Determinine Bearing Capacity And Elastic Settlement Of Foundations, Vahidreza Mahmoudabadi Arani
All Dissertations
This dissertation presents a coupled hydrological-geotechnical framework to investigate the performance of shallow and deep foundations under hydrological events such as heavy rainfall and drought. The variation in performance of foundation, interface between the structure and ground surface, is caused by the uncertainties associated with not only the geotechnical parameters but also the hydrological parameters that include intensity and duration of hydrological events and water table depth. The impact of such hydrological events significantly alters the performance of foundations by changing the soil strength and stiffness parameters of subsurface soil which may lead to foundation failures. Such failures can cause …
