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...
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...
Settlements of Highway Embankments on Soft Lacustrine Deposits
This paper presents the settlement study that was conducted in conjunction with the major freeway expansion project planned through Salt Lake City in which existing embankments will be...
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...
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...
Settlement Predictions Using Piezocone
Detailed data on settlement predictions and measured values are given for two water tanks and an area of fill constructed on a thick soft clay stratum that showed decreasing preconsolidation...
Performance of a Steel Tank Founded on a Marine Clay
For tanks on soft clays, the soil is often preloaded before tank construction to increase bearing capacity and minimize post-construction settlement. In the case history described here,...
Long Term Performance of Raft and Footing Foundations Above Clayey Silt
Two multistorey buildings have recently been constructed on a 30-m thick layer of clayey silt in downtown Fredericton, New Brunswick. The Bank of Montreal building is ten storeys high...
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...
The Influence of Engineering Judgement in the Settlement Analysis of a Test Fill Near Ch?lon-sur-Sa?ne, France
This paper describes the settlement study for a test fill near Chalon-sur-Saone (France). The soil profile at the site comprised a silty clay layer 4.2 m thick. The elevation of the ground...
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 of Test Fills for Chek Lap Kok Airport
Lateral Foundation Deformations for a Marine Test Fill
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...
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...
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....
