Graphic Visualization for Planning Heavy Lifts
The application of graphical visualization to construction can serve a wide variety of objectives and offers many significant benefits. Heavy lifts are an important component of industrial...
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...
Compressibility of Clays: Fundamental and Practical Aspects
The compressibility of natural clays is influenced by strain rate, temperature, sampling disturbance, stress path and some restructuration factors. The first part of the paper reviews...
Methods to Reduce the Settlement of Embankments on Soft Clay: A Review
New trends have been observed during the past ten years in the practice of settlement control for embankments on soft clays: they include increased use of rigid (piles) or semi-rigid (stone...
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...
Testing and Predicting the Movement of a Drilled Shaft in New Mexico
The New Mexico State Highway and Transportation Department (NMSH&TD) have been using drilled shafts for supporting bridges in the State of New Mexico. Several drilled shafts were...
Replacement of a Failed Embankment Designed to Accommodate Large Settlement: A Case Study
Thick deposits of soft, normally to slightly preconsolidated, organic clay are common at low elevations along the riverbanks of southeast Texas. Both the moisture content and liquid limit...
Settlement Analysis of Landfill Liners over Deep Mined Areas
Tensile strains due to differential settlement from past mining activities were evaluated for a landfill liner. The landfill cell encompasses 20 acres and is located on a subsurface profile...
Preloading Organic Soils to Limit Future Settlements
This paper presents the authors' experience in preloading organic soils in south Florida to allow the construction of roadways, utilities, and low-rise residential structures on shallow...
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...
Nonlinear Undrained Lateral Response of Rigid Drilled Shafts Using Continuum Theory
The nonlinear undrained response of rigid drilled shafts under static lateral and moment loading is evaluated within the context of elastic continuum theory. The approximate approach utilizes...
Cyclic Loading for the Measuring of Soil Consolidation Parameters
A method of determination of soil consolidation characteristics using sinusoidal loading is described. It can be performed in laboratory test or in situ observation as well, with different...
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...
Performance of Three Large-Diameter Oil Tanks on Soft Clay
Preloading using a clay surcharge at the proposed locations of 3 large-diameter steel oil storage tanks founded on a 20-m thick stratum of soft Nile-delta silty clay produced about 1.5...
Settlement Measurements of 50-ft High Embankments at the Chesapeake & Delaware Canal Bridge
This is a case history of instrumented settlement measurements on 49 to 56' (15-17 m) high bridge approach embankments of Delaware State Route 1 crossing of the Chesapeake & Delaware...
Compressibility for Sand Under One-Dimensional Loading Condition
Empirical equations for one dimensional compression of sand do not include parameters characterizing properties of sand grains (e.g. moduli, size and shape of sand grains, and friction...
The Role of Shale Pores in Settlement
Waste fills resulting from the mining of coal in Appalachia should ideally consist of large, free-draining sedimentary rock fragments. The successful performance of these embankments is...
Settlement of Peats and Organic Soils
New advances in investigation of settlement of peats and organic soils and issues related to construction over such soft ground are presented. Peats and organic soils are well known for...
Settlement of Dynamically Compacted Deposits
This paper compares predicted and measured settlements of deposits that were densified by means of dynamic compaction. Settlement records are presented for sites consisting of old, midage,...
