Design of Underpinning Piles to Reduce Settlements
Piles are frequently used to underpin structures which have suffered, or are expected to suffer, damage due to excessive settlement or differential settlement. However, existing methods...
Measured Downdrag on Seven Coated and Uncoated Piles in New Orleans
A site outside of New Orleans, Louisiana was selected as part of a research effort to study the phenomenon of downdrag on bitumen-coated piles. Two steel pipe piles, two timber piles,...
Comparison of Settlement Predictions for Single Piles in Sand Based on Penetration Test Results
The analysis of settlement for driven piles in cohesionless soils is a complex soil structure interaction problem. The total settlement for such a pile is generally considered to be the...
The Tip Displacement of Drilled Shafts in Sands
The design load of large diameter drilled shafts is determined so that the settlements do not exceed the values associated with the ultimate and serviceability limit states. Based on the...
Footing Modulus Near Slopes
A method is described for estimating the footing modulus of shallow spread foundations located near slopes of cohesionless material. The ratio of footing modulus for a shallow foundation...
Settlement and Deformation Response of a Bridge Footing on a Sloped Fill
The problem of settlement of spread footings located within or near granular slopes has been investigated in the laboratory using a large testing facility. Based on these results, footings...
Consolidation Settlements and Pore Pressure Dissipation
A test fill was constructed off the coast of one of the outer islands in Hong Kong to evaluate the consolidation characteristics of a soft plastic clay deposit known as Hong Kong mud....
Settlement of Deep Compacted Fills in California
Measured settlement of deep compacted engineered fills from a single site were summarized and compared to data from other sites. The data indicate that the rate and magnitude of movement...
Modeling Settlements of an Existing Municipal Solid Waste Landfill Sideslope Using an Earthen Surcharge Pile
This paper discusses the results of a large-scale field compressibility test completed on municipal solid waste (MSW). The test consisted of surcharging the waste mass with an earthen...
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...
Comparison of Predicted and Measured Settlement of a Test Embankment Over Soft Soil
A test embankment was instrumented with six (6) settlement plates, three (3) vertical extensometers, two (2) inclinometers, and two (2) horizontal profilers in order to verify settlement...
Compaction Grouting Stops Settlement of an Operating Water Treatment Plant
In early 1978, about a month into full-time operation, the new filter plant building for the water treatment plant for the City of Glenwood Springs, Colorado, experienced distress due...
Performance of Wick Drains Installed by Vibration
Settlement and piezometer data from construction of fills on Route I-291 in South Windsor, CT is analyzed for total settlement and coefficient of consolidation. The results are compared...
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...
Vacuum-Assisted Consolidation of a Hydraulic Landfill
As part of the Pier 300 42-acre site ground modification project, a field test of vacuum-assisted preconsolidation of hydraulic fill was studied. The objective of the test was to assess...
Consolidation of Ground Reclaimed by Inhomogeneous Clay
A large amount of prefabricated band drain was installed to improve the ground reclaimed by soft soils at the enlargement project of the Tokyo International Airport. By analyzing data...
Field Test of Thermal Precompression
A new concept for improvement of soft ground using moderate heating to control post-construction settlement is presented. The long-term creep behavior of a peat is presented based on laboratory...
