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...
Settlement of Footings on Granular Materials: Low and Large Strain Parameters
Many methods have been proposed to predict the settlement of shallow foundations on granular soils. The analysis of more than 200 case histories shows that there is no correlation between...
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...
Application of the Diflupress L.D. Field Test to Settlement Calculation
Electricite de France developed a new in situ measurement apparatus (Diflupress L.D.) in order to predict the delayed settlements that can appear under heavy constructions. From the experimental...
Measurements and Numerical Modelling of High Rise Building Foundations on Frankfurt Clay
Many high rise buildings were founded on Frankfurt clay on rafts applying average contact stresses in the order of 0.4 MPa. Beside rafts now piled-rafts are often used to reduce total...
Management of Dredged Material Placement Operations
Non-linear finite strain consolidation theory is used to predict the settlement of fine-grained dredged material due to self-weight and surcharge-induced consolidation. Finite strain consolidation...
Numerical Modeling of Bridge Approach Settlement with Foundation-Embankment Interaction
Bridge approach settlement is one of the major problems facing the transportation agencies responsible for road construction and maintenance in the United States and in many other countries...
Consolidation Characteristics of an Offshore Clay Deposit
This paper summarizes the results from a comprehensive laboratory and in situ investigation of an offshore clay deposit in the northeastern coast of Brazil. Laboratory permeability data...
Collapse Mechanism of Compacted Clayey and Silty Sands
The mechanism of wetting-induced collapse (hydrocompression) and the influence of fines ratios on compacted sandy soils are investigated. Various ratios of clay and silt are mixed with...
Rate of Settlement of Silt Alluvium at Trojan
Settlements of 1.83 m have been observed at the switchyard of the Trojan Nuclear Power Plant over a 22-year period since 1970. Rockfill had been placed on the site, a flood plain of the...
Tree Root Induced Settlement of a Large Industrial Building Founded on Expansive Clay?A Case History
Trees planted adjacent to buildings have been known to cause significant structural distress. In this paper, a case study is presented where a large tilt-up concrete industrial building...
Damage Evaluation of Building on Piers in Expansive Clay
A number of columns in the crawl space of a pier-supported structure founded in expansive clays were damaged as a result of ground movements since the building was constructed in 1975....
Settlement of Building Foundations on Clay Soil Caused by Evapotranspiration
This paper reports on the results of a field investigation and settlement monitoring program which involves five buildings founded on shallow foundations in the sensitive clay deposits...
The Behavior of a Building with Shallow Foundations on a Stiff Lateritic Clay
The use of shallow foundations for buildings in Sao Paulo, either on soils of the Tertiary Sedimentary Basin of Sao Paulo (TSBSP) or on those of saprolitic origin is not as frequent as...
Settlement of Compacted Fills Caused by Wetting
Post-construction wetting of fills can cause swell or compression, depending on soil composition and stress conditions just before wetting. The various factors affecting swell/compression...
Case History of a Collapsible Soil Fill
Collapse settlement of a deep compacted fill led to damage of a group of condominium units. The fill consisted of a highly heterogeneous mixture of coarse- to fine-grained soil containing...
