An International Knowledge Database for Ground Improvement Geo-Systems
Ground improvement technologies have traditionally played an integral and important role in major geotechnical construction projects throughout the history of civil engineering and selection...
Analysis of Port Allen Lock in Elastic-Plastic Soil Medium
Incremental finite element analyses using Drucker-Prager plasticity model are applied to study the interaction of Port Allen Lock with its surrounding soil. The analyses not only consider...
A Simplified Method of Multistory-frame Analysis Including the P-? Effect
A simplified method of non-iterative analysis of rigid multistory-frames having vertical columns with different heights within the same story is developed by means of a modification to...
Expert System for Bridge Scour and Stream Stability
Significant engineering judgment is required to ascertain the scour susceptibility of bridges. This judgment is typically acquired through many years of experience. This paper describes...
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 Evaluation for Cap Closure Performance
Predicting short and long-term performance of a landfill cap system is a difficult task considering the generally unknown nature of the waste and magnitude and variation of settlement...
The Control of Settlement Using Geogrids
The applicability of geogrids in reducing settlements has been investigated in the laboratory in two separate studies, in unpaved roads under cycled load applications, and as overlays...
An Investigation of the Reinforcing Effect of Stone Columns in Soft Clay
A proposed major extension to an iron ore handling yard was located in an area underlain by soft alluvial clay. Stone columns were proposed to limit settlement of rails supporting the...
Reduction of Settlements Using Soil Reinforcement
This paper presents the experimental and finite element method (FEM) of analyses performed to model the use of soil reinforcement for rehabilitation of gantry crane track foundations....
Strip Foundation on Geogrid-Reinforced Clay
Laboratory model test results for the ultimate bearing capacity and allowable bearing capacity at various settlement levels conducted on a strip foundation supported by geogrid-reinforced...
The Usefulness of Stone Columns to Reduce Settlements and Distortions - A Case History
A shed had to be built as a storage area for ashes and gypsum resulting from the combustion of coal in a power plant in Sardinia, Italy. Two field loading tests have been performed. In...
Settlement Predictions at a Florida Port Facility
A paved container storage area approximately four acres in size has been constructed at the existing Port of Fernandina in Fernandina Beach, Florida. Approximately one-half of the site...
Geocell Mattress Effects on Embankment Settlements
Laboratory investigations and finite element analyses of geocell mattresses beneath embankments were performed to determine the effect of such mattresses in reducing settlements. Eight-foot...
Settlement of Large Mat on Deep Compressible Soil
This case history describes the settlement analyses for a large load compensated (floating) mat foundation on a deep deposit of normally consolidated clay of variable thickness. Large...
Influence of Flexible Mat on Settlements of Marine Clay
Highly compressible marine clays occur extensively in coastal regions. In lieu of traditional pile or raft foundations in such weak soils, recently a flexible mat system has been developed...
Settlement of Structures Supported on Marginal or Inadequate Soils Stiffened With Short Aggregate Piers
A short aggregate pier system, which was developed to provide an economical alternative to the overexcavation/replacement technique, has been used since 1988 to control settlement of structures...
Building Performance Founded on an Improved Sand in Recife, Brazil
Studies performed on a fourteen-storey building founded on an improved sand are presented. These studies included soil profile characterization, the choice of foundation type, the ground...
Soil Improvement to Mitigate Settlements under Existing Structures
Settlements of sites with existing structures are more difficult to mitigate than those of sites without structures. Equipment access, work area, noise, dust, vibrations, and cost are...
A Comparison of Three Soil Improvement Techniques to Densify Liquefaction Susceptible Sands
Deep soil densification programs using vibratory probe compaction, vibro-replacement and terraprobe methods have been completed on a naval submarine base to limit potential settlements...
Vacuum consolidation Technology?Principles and Field Experience
Vacuum consolidation is an effective means for improvement of saturated soft soils. The soil site is covered with an airtight membrane and a vacuum is created underneath it by using a...
