PRESENTATION TITLEKey Technologies of Tunnel Disaster Prevention and Informationization Construction

PRESENTATION SUMMERY – Nowadays, tunnel construction is playing an important role in the construction of railway, highroad as well as urban railway system. However, the safety and efficiency of tunnel construction mainly depends on the detection of the extremely complex adverse geological conditions, and constructors’ safe operation. For the ahead prediction of tunnel adverse geological bodies, in-tunnel induced polarization is used to estimate the water volume, with special instrument on TBM in Yinsong project, Jilin province. 3D seismic prospecting method and software system is designed to detect fault fracture zone in front of tunnel face and it has successfully applied in Wudongde hydropower station, Lanzhou-Chengdu railway project, Yinsong project, and subway project in Xiamen. 3D resistivity computed tomography method and software is developed for boulder detection in metro shield tunnel. To deal with the data produced in the construction of TBM/shield tunnel, tunnel construction information system is built based on the big data technology. It provides the platform to optimize the design of TBM/shield machine and the selection of its type, thus improve the drivage efficiency and control the cause of accident. As for the informationization of tunnel construction, the internet of things technology is applied to combine the actual tunnel with its digital tunnel to bring forward the idea of ‘intelligent tunnel’. Based on the advantage of ‘Cloud computing’ and big data technology, it can provide intelligent services for making decisions. Therefore, through all these technologies, we can greatly improve the level of tunnel disaster prevention and informationization construction.

PRESENTATION TITLE – Geotechnical Considerations for Mega Projects in Mexican Infrastructures

PRESENTATION SUMMERY – In Mexico, there are several mega civil infrastructure projects, located in challenging geotechnical conditions. Examples include, a 225 km long subway system, developed between 1969 and 2012 on very soft clay in Mexico City and a project for the New Mexico City Airport, with 6 runways in a site with extremely soft clay, with high water content, low resistance, and poor characteristics in deformability. Additional examples of geotechnically challenging mega projects include high dams, such as the 261 meter high Chicoasen Dam, constructed in 1980 with rockfill with clay core and the 187 meter high Aguamilpa Dam, a concrete face rockfill dam (CFRD) constructed in 1997. Both these dams were the highest dams for their types at the time of their construction and were followed by other very important dam constructions, such as the El Cajon and the La Yesca dams, with 188 and 220 meters of height, respectively.

In addition to the challenging soil conditions, each of these projects have a common adverse factor in the form of seismic activities. Mexico City and the East and South regions in Mexico can be under a very strong motion from seismic activities.

Overall, the geotechnical engineers have learnt important lessons on the local and regional geotechnical conditions through solving the unique challenges faced on these projects, in order to warrant safety during construction and for the behavior of the structures in the operation period in each case.

PRESENTATION TITLE – The Future of Design: The Role of Instrumentation and Feedback in Heavy Civil Engineering

PRESENTATION SUMMERY – Civil Engineering design in the United States has gone through amazing evaluation over the last few decades, going from hand drafting to BIM and 3-D printing and from optical surveying to GIS and remote sensing. At the same time, the design and operating procedures are still very much based in prescriptive code based design. The designers still tend to take a more “design-build-walk away” approach towards their projects, while the clients are focusing more on life cycle implications of design and construction with the development of the Internet of Things and Smart Infrastructure. Large infrastructure managers are beginning to look at their systems holistically; collecting key performance metrics on systems, which in turns has resulted in a doubling of utilization of data acquisition equipment in heavy civil engineering applications in recent years. This is interesting because many of these decisions are being made in response to demands that come from stakeholders who are not engineers—owners and politicians and managers who understand what they want to know so that they can effectively manage their infrastructure inventory, but that do not understand how to get those data.

Civil engineering, as a profession, is at a pivotal moment in its development and growth. There is a clear interest in and demand for these data, and civil engineers are the right professionals to be doing the necessary work, but there is a disconnect in the expertise. The civil engineers know what needs to be measured and reported, but they do not know how to do it. The focus of this presentation is to help civil engineers understand how instrumentation is evolving, and how to develop the skills and expertise necessary to do this work.

PRESENTATION TITLE – Productivity of The Transportation Infrastructure System

PRESENTATION SUMMERY – Productivity is defined as the state or quality of yielding results or benefits to the satisfaction of wants or the creation of utilities. Combined with transportation infrastructure, the term (Transportation Infrastructure Productivity - TIP) thus contains the idea that said infrastructure should be used to the benefits and satisfaction of that which is being transported, be it people or goods. Provision, operations and maintenance of transportation infrastructure is typically the focus of engineers. However, many issues can cause this infrastructure to be less productive than it should be, and therefore lead to wastage.

This lecture focuses on aspects of the transportation infrastructure lifecycle where improved productivity can be defined, measured and used to the benefit of society. It starts with analysis of construction productivity, with specific reference to the use of appropriate materials to construct sustainable infrastructure. In the maintenance phase the focus is on the effect that road maintenance scheduling can have on road user experiences and productivity, as well as the effect of adequate road maintenance on the cost of transportation of agricultural freight and the potential damage caused to such freight. The operations phase focuses on evaluation of the effect of traffic light synchronization on transportation efficiency and the difference that performance-based standards for trucks can have on road safety and productivity. The concepts are illustrated through reference to data from case studies in South Africa.
