Prediction of Ground Deformations Due to Excavation-Application to Tunnel Lining Design in Weak Rock
Prediction of ground deformations due to excavations is simulated by three dimensional non-linear finite element analyses. It considers various in-situ ground stress levels, excavation...

Three Dimensional Simulation of Progressive Tunneling Process for Lining Design of Intersecting Tunnels in Soft Rock
This paper presents the results of the state-of-the-art three-dimensional nonlinear finite element modeling of progressive tunneling process and its comparison with field data. Reasonable...

A Version and Configuration Scheme for Collaborative Engineering
This paper presents a data management model for collaborative design. Versions are proposed to support the independent evolution of design alternatives in an individual discipline. configurations...

Database Integration in Support of Construction Management
This presentation will describe how new object-oriented technology is being applied to this problem. The goal of this use of object-oriented systems is 1) to provide a method for processing...

A Computerized Methodology for Conducting Pedestrian Gap Studies
this paper will detail recent improvements with the procedure the New York City Department of Transportation utilizes when conducting Pedestrian Gap Studies. These improvements were made...

Quick Checks for Structural Computer Analysis
When working with general structural analysis programs, there are some fast ways to check the input and output. This paper reviews some methods for verification of results of computerized...

A Real-Time Graphical Interface to a Two-Dimensional Groundwater Flow and Mass Transport Model
This paper describes the implementation of a graphical interface to the U.S. Geological Survey's Method of Characteristics (MOC) groundwater flow and mass transport model....

Facilitate Delay Claim Analysis with As-Built Schedule Databases
A computer-based As-Built Schedule Database can provide a useful tool for the investigation of project performance. The facts recorded in the database may be used to identify actual sequential...

Computer Use in Claims Analysis -- Roundtable Discussion
Preparation or defense of construction claims is inherently time consuming and often counter-productive. This outline discusses some tools currently used in the construction industry to...

CadVisor (CAD Equipment Analysis and Selection System)
This paper describes a system called CadVisor (CAD Equipment Analysis and Selection System) developed by the U.S. Army Corps of Engineers Construction Engineering Research Laboratories...

Management Information System Application on a Multi-Million Overseas Project
Project Management Information Systems (PMIS) provides improved data quality, consistency, timeliness, and reporting flexibility and improved project teamwork. Project managers have a...

Conceptual Design Using Evolutive-Cognitive Computing Techniques
The paper concerns the development of a computer-based capability for conducting conceptual design using emergent(self-organizing) computing paradigms that arrive at a solution through...

Use and Abuse of Settlement Analysis
Terzaghi's concept of settlement analysis included comparison of prediction with reality and investigation of the causes of the differences. Present usage is often limited to prediction....

Settlement of Embankments on Soft Clays
It is now possible to make reliable predictions of settlement of embankments on soft clays. In most situations, where the embankment is designed to resist undrained instability during...

Settlement of Tanks on Clay
Steel tanks for storage of water, oil, and other liquids are capable of withstanding large, but not unlimited, settlements without damage. In most cases shallow foundations provide adequate...

Mat Foundation Design: An Historical Perspective
Nearly a half century ago, Karl Terzaghi rationalized the analysis and design of mat foundations with the conclusion that subgrade reaction was the most important variable. Soon after...

53 WAK Tests on Spread Footings
Research on the prediction of soil stiffnesses of spread footing-soil systems using Wave Activated Stiffness (K) or WAK tests was conducted. As discrete lumped-parameter model with a mass,...

Vertical and Horizontal Deformations for Foundations on Sand: An Experimental Study
A natural scale model is used in order to investigate experimentally the sand soil deformation behavior which accepts loads by shallow foundations. The vertical and horizontal soil displacements...

Settlement Behavior of an Avalanche Protection Gallery Founded on Loose Sandy Silt
An avalanche protection gallery located in the Swiss Alps was founded on alluvial ground close to the steep rocky mountainside. The rear retaining wall, at a variable distance of a few...

Displacement of Landmark Building Resulting from Adjacent Construction Activities
This paper describes the observations and presents comments related to the measurement of settlement and the avoidance of damage to a historic structure in the City of New York from adjacent...
