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...
KBES Applications to the Selection and Design of Retaining Structures
Knowledge-based expert systems (KBES) are computer programs, based on artificial intelligence (AI) techniques, designed to reach the level of performance of a human expert in some specialized...
Evaluation of Geotechnical Design Parameters by Expert System Techniques
This study refers to application of an artificial intelligence technique to evaluate geotechnical design parameters in the soil design definition. This complex evaluation is incorporeted...
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...
Use of a Tie-Back Retaining Wall to Stabilize a Moving Landslide
After failure of a gravity retaining wall, a moving landslide was stopped and stabilized by a tie-back retaining wall. The design considered the active landslide and residual strength...
Watertight and Earthquake Resistant Joints for Diaphragm Walls
Different types of joints were constructed and tested in the field to evaluate the bond between concrete and partition plate, the effect of tremie pipe location to the quality of concrete...
