The Effect of Loading Rate on the Bending Strength of Alluvium Reinforced Ice
Traditional building materials are often less than ideal for construction in remote Arctic locations. Their mechanical properties may be degraded in extreme cold, and costs associated...

Experimental Study of Adfreeze Heaving of Augered Caisson Footings
In order to establish the required depth of augered caisson-type footings in cold regions and their optimal design against adfreeze heaving, an experimental field investigation has been...

River Ice Cover Cracking for Various Boundary Conditions
The breakup of river ice covers is commonly initiated by the formation of cracks parallel to river banks. These cracks usually result from a change in the water level due to a rapid rising...

Earth Walls: Making the Right Choice
Earth walls are retaining walls where the ground assumes a load-bearing role. These walls either support compacted earth (embankment-type reinforced compacted earth walls such as Doublewal...

Dallas' Flood Caverns
Dallas' North Central Expressway floods during heavy rains, but the dense development that helps create excessive runoff also precludes large detention ponds. The high-quality,...

Active Control of Structures with Soil-Structure Interaction
The objective of this paper is investigate the effect of soil flexibility on the performance of the active control system for seismic-excited buildings. By using the critical-mode control...

Design of a Neural Network Power Grasp Controller
An overview of research on the development of an artificial neural network controller used to implement power grasping on the DIGITS Grasping System is presented. The DIGITS System, under...

Nonlinearities and Imperfections in Creep Stability
The effects of material and geometric nonlinearities and imperfections on the 'safe-load-limit' and the 'safe-service-period' of structures...

Minimum Required Lateral Stiffness of Structures
In this paper an approximate method is presented to calculate the minimum lateral stiffness required to insure global structural stability. The technique is based on setting the critical...

Large Displacement Analysis for Structural Stability Problems
In this paper, two widely different methods of large displacement analyses are considered. The first is a discrete element analysis which is particularly effective for line structures...

Dynanmic Stability and Seismic Response of Damped Beams in the Presence of Follower Forces
The dynamic stability and the seismic response of general beams are examined, by discretizing the structure to a set of rigid bars, linked together by means of elastic constraints (Cells...

Public Involvement in the Safety Monitoring of Dams, Embankments and Slopes
New methods of safety monitoring of dams, embankments and slopes require automated data acquisition, data transmission and computer based data evaluation to provide immediate safety information...

A Hybrid Expert System for Design with Geosynthetics
A prototype hybrid expert system is presented that selects geosynthetic materials and performs detailed designs for different geotechnical applications. An expert system is used to give...

An Expert System for Estimating Soil Strength Parameters
An expert system to aid in selecting shear-strength parameters for use in stability analysis was developed for use on a PC. It provides guidance in interpreting strength measurements and...

Soil-Cement Mixed Wall Technique
This paper introduces the soil-cement mixed wall technique and its applications for the installation of cutoff walls, excavation support walls and soil-crete columns for soil stabilization....

Stabilization of Collapsible Alluvial Soil Using Dynamic Compaction
The effectiveness of dynamic compaction for improving collapsible soils was evaluated under field conditions using full scale load tests performed on 1.5 m square footings. Tests were...

Jet Grouting?Uses for Soil Improvement
The frequency of use of any engineering technique depends mainly on the technical feasibility and economics of the system. In geotechnical engineering, the more problems a construction...

An Expert System for Preliminary Ground Improvement Selection
Ground Improvement is an area which has rapidly advanced in the past two decades. Most of the work has resulted from experience in field work. Thus experience has played a vital role in...

Reliability in Rock Engineering
This paper reviews approaches to reliability in rock engineering through a survey of methods developed at MIT. Since these methods are intended to be applied in engineering decisions,...

Methodology for Optimizing Rock Slope Preventative Maintenance Programs
Rock slopes along transportation routes can fail in several different modes, with various types and magnitudes of consequences. The 'risks' associated with such...
