International Conference on Civil Infrastructure and Construction (CIC 2020)
This is the proceedings of the CIC 2020 Conference, which was held under
the patronage of His Excellency Sheikh Khalid bin Khalifa bin Abdulaziz Al
Thani in Doha, Qatar from 2 to 5 February 2020. The goal of the conference
was to provide a platform to discuss next-generation infrastructure and its
construction among key players such as researchers, industry professionals
and leaders, local government agencies, clients, construction contractors and
policymakers.
The conference gathered industry and academia to disseminate their research
and field experiences in multiple areas of civil engineering. It was also a unique
opportunity for companies and organizations to show the most recent
advances in the field of civil infrastructure and construction.
The conference covered a wide range of timely topics that address the needs
of the construction industry all over the world and particularly in Qatar. All
papers were peer reviewed by experts in their field and edited for publication.
The conference accepted a total number of 127 papers submitted by authors
from five different continents under the following four themes:
Theme 1: Construction Management and Process
Theme 2: Materials and Transportation Engineering
Theme 3: Geotechnical, Environmental, and Geo-environmental Engineering
Theme 4: Sustainability, Renovation, and Monitoring of Civil InfrastructureThe list of the Sponsors are listed at page 1
Earth pressure balance (EPB) shield tunneling in Bangkok : ground response and prediction of surface settlements using artificial neural networks
Thesis (Sc.D.)--Massachusetts Institute of Technology, Dept. of Civil and Environmental Engineering, 2002.Vita.Includes bibliographical references.Although Earth Pressure Balance (EPB) shields have been used for several decades, very little information exists about the actual mechanisms of shield-ground interaction. The ground response mechanism induced by EPB tunneling is difficult to understand, because this requires not only reliable ground deformation measurements in the field but also operational records of the shield. Numerous empirical and analytical relations between characteristics of traditional shields and surface and subsurface deformations exist; also 2-D and 3-D numerical analyses have been applied to such tunneling problems. However, very few approaches have been developed for EPB tunneling. This research makes use of the fact that in the Bangkok MRTA project, data on ground deformation and shield operation were collected. The tunnel sizes are practically identical and the subsurface conditions over long distances are comparable, which allow one to establish relationships between ground characteristics and EPB-operation on the one hand, and surface and subsurface deformations on the other hand. A computerized database, which records much of the information on a ring-by-ring (1.2 meter interval) basis, was developed for this purpose. After using the information to identify which ground- and EPB-characteristic have the greatest influence on ground movements, an approach based on Artificial Neural Networks (ANN) was used to develop predictive relations. Since the method has the ability to map input to output patterns, ANN enable one to map all influencing parameters to surface settlements.(cont.) Combining the extensive computerized database and the knowledge of what influences the surface settlements, ANN can become a useful predictive method. This research attempts to evaluate the potential as well as the limitations of ANN for predicting surface settlements caused by EPB shield tunneling and to develop optimal neural network models for this purpose. Specifically, this involves settlement predictions over the tunnel axes of single and twin tunnels; together with other interpretations, it is also possible to predict settlement troughs. Other shield effects such as lateral deformation and liner deformation of the first tunnel caused by the second tunnel are also evaluated.by Suchatvee Suwansawat.Sc.D

HE-LHC: The High-Energy Large Hadron Collider: Future Circular Collider Conceptual Design Report Volume 4
Abstract: In response to the 2013 Update of the European Strategy for Particle Physics (EPPSU), the Future Circular Collider (FCC) study was launched as a world-wide international collaboration hosted by CERN. The FCC study covered an energy-frontier hadron collider (FCC-hh), a highest-luminosity high-energy lepton collider (FCC-ee), the corresponding 100 km tunnel infrastructure, as well as the physics opportunities of these two colliders, and a high-energy LHC, based on FCC-hh technology. This document constitutes the third volume of the FCC Conceptual Design Report, devoted to the hadron collider FCC-hh. It summarizes the FCC-hh physics discovery opportunities, presents the FCC-hh accelerator design, performance reach, and staged operation plan, discusses the underlying technologies, the civil engineering and technical infrastructure, and also sketches a possible implementation. Combining ingredients from the Large Hadron Collider (LHC), the high-luminosity LHC upgrade and adding novel technologies and approaches, the FCC-hh design aims at significantly extending the energy frontier to 100 TeV. Its unprecedented centre-of-mass collision energy will make the FCC-hh a unique instrument to explore physics beyond the Standard Model, offering great direct sensitivity to new physics and discoveries
