Preface This is the fourth volume of six Geotechnical Special Publications (GSPs) and one Geotechnical Practice Publication (GPP) containing papers from the 2018 Intern
10、ational Foundations Congress and Equipment Expo (IFCEE18) held in Orlando, Florida on March 510, 2018. The IFCEE conference series combines a technical conference and equipment show dedicated to the design and construction of foundation systems, using the latest geo-engineering and geo-construction
11、technologies and practices. The IFCEE conference series is a one of a kind event that attracts attendees from around the world for the worlds largest equipment exposition dedicated solely to the deep foundations industry. This Congress combined the 2018 annual meetings of ASCEs Geo-Institute, the In
12、ternational Association of Foundation Drilling (ADSC), the Pile Driving Contractors Association (PDCA) and the Deep Foundations Institute (DFI). This event was the third Congress in the IFCEE conference series, following the successful 2009 and 2015 meetings, in which these leading geotechnical and
13、geotechnical-related organizations joined together for a single and singular annual congress. IFCEE18 provided an international forum to discuss technological advances, case histories, and present challenges related to geotechnical and foundation engineering. The Congress was attended by a wide rang
14、e of geo-professionals including engineers, contractors, academicians, equipment manufacturers, geo-technologists, researchers, and service, material and tooling suppliers. This publication culminates two years of effort by the technical planning committee whose focus has been to continue the succes
15、s of the previous meetings in the IFCEE conference series. Many individuals are responsible for the content of this volume, all of whom served in the efforts to maintain the standard set by previous proceedings. An international call for papers and a rigorous peer review process yielded 280 accepted
16、 technical papers, that were presented in 47 sessions, in addition to invited keynote presentations. Papers were reviewed in accordance with ASCE GSP standards. Accordingly, each paper was subjected to technical review by two or more independent peer reviewers. Publication requires concurrence by at
17、 least two peer reviewers. The Editors would like to express their appreciation for having been provided the opportunity to be a part of this Congress organization, their sincere thanks to the numerous session chairs and reviewers, and we hope that these proceedings will be of use to the geotechnica
18、l engineering community for many years to come. The Editors, Anne Lemnitzer, Ph.D., A.M.ASCE, M.DFI, University of California, Irvine Armin W.

This cofferdam stage represented 20% of the total excavated volume of this project and caused about a th

An axisymmetric numerical model using an advanced constitutive soil model, the hypoplasticity model for clays with intergranular strains, is developed to simulate an idealized lower bound solution of the ground movements resulting from the OMPW cofferdam excava

41、ultants, 2141 Palomar Airport Rd., Carlsbad, CA 92001. E-mail: Abstract The performance of a circular cofferdam braced with reinforced concrete ring beams is presented in this paper. The cofferdams were built using a continuous circular wall, made of interlocked sheet pile modular pieces, internall
42、y braced with ring beams. During concrete placement of the exposed ring beams, curing conditions were affected by temperatures below the freezing point of water which resulted in lower concrete strength and stiffness values than those estimated during the design phase. A numerical model is presented
43、 to study the influence on the performance of creep, shrinkage, temperature, and aging of concrete. Lateral wall displacements are computed with the model only as a result of coupled temperature and concrete time-dependent effects and studied individually with a parametric study. Those effects contr
44、ibuted about 17% of the total maximum measured lateral wall deformations. Creep effects had the largest contribution with about 8%, while aging of concrete and shrinkage contributed less than 5%. INTRODUCTION In modern construction of high-rise structures, the use of temporary cofferdam structures t
45、o build the lateral load resisting system of the building has increased. However, excavation-induced ground movements in urban cofferdams are often ignored because they are considered as temporary structures and represent only a small part of a major excavation sequence. These ground movements might

SUMMARY OF OBSERVED PERFORMANCE Figure 2 illustrates the cofferdam layout, construction sequence followed during the cofferdam installation and excavation, and the lateral wall deformations measured with
47、 inclinometer I-1 installed next to the cofferdam. The installation of the cofferdam started by leveling the ground surface to a depth of about 0.6 m, at which the sheet piles started to be driven. The temporary cofferdam was excavated following accelerated cycles of soil removal and concrete ring b
48、eam placement until the bottom of cut was reached. The excavation inside the cofferdam was temporarily stopped at construction day 115 (i.e., end of construction of sixth concrete ring beam level, RB6) to install deep foundations to support the building rigid core walls.
