Deep Learning Model

Currently, unmanned aerial vehicles are increasingly being used in various construction projects such as housing developments, road construction, and bridge maintenance. If a drone is used at a road construction site, elevation information and orthoimages can be generated to acquire the construction status quantitatively. However, the detection of detailed changes in the site owing to construction depends on visual video interpretation. This study develops a method for automatic detection of the construction area using multitemporal images and a deep learning method. First, a deep learning model was trained using images of the changing area as reference. Second, we obtained an effective application method by applying various parameters to the deep learning process. The application of the time-series images of a construction site to the selected deep learning model enabled more effective identification of the changed areas than the existing pixel-based change detection. The proposed method is expected to be very helpful in construction management by aiding in the development of smart construction technology.

Geological Conditions

Since the 21st century, the national economy of China has tended to fast develop, and the people's material life has been greatly improved. As the investment of the state in social infrastructure continues to increase, the domestic infrastructure construction has been in a rapid development, and especially the road and bridge construction projects have largely accelerated the development of the transportation and also the growth of the national economy in China. In the meantime, the geological conditions encountered in highway engineering are more and more complicated, so the requirement on the construction technology is continuously higher and higher, and finally certain difficulties are caused to the construction. In this paper, the construction technology of the graded granular cushion at the bottom of the subgrade in highway engineering is studied and discussed specifically.

AbstractThe work contains information on the implementation of surveying works in the road construction process. The aim of the research was to identify geodetic risk factors occurring at the stage of preparation of a construction project, the presence of which can greatly disrupt the undertaking such as the road construction. The research was carried out on the basis of expert knowledge, documentation obtained from various road construction projects and the analysis of disturbances at the initial stage of works.
