Seepage Studies Using Tracers and the Self Potential Test
Mill Creek Dam, a homogeneous silt structure resting on a conglomerate foundation, has experienced severe 'seepage since its construction in 1941. In 1981, a concrete cutoff...
Analysis of Liquefaction Potential by Insitu Testing
This paper describes the results of insitu testing performed to assess the liquefaction potential of a sand formation at a site for a proposed large industrial facility in East Central...
A Relationship Between Deformation Modulus and SPT N for Gravels
The results of over 200 horizontal plate load tests performed in situ in large diameter boreholes on gravels at various relative densities are used to develop a relationship between deformation...
The Use of Cone Penetrometer Testing to Investigate Sand Fill Subsidence Beneath Highways
During construction of Interstate I-10 between Baton Rouge and LaPlace, Louisiana, highly organic swamp deposits were excavated and replaced with hydraulically pumped river sand. The main...
In Situ P and S Wave Velocity Measurement
A review of the in situ techniques to measure P and S wave velocities by seismic wave propagation is presented. A relatively new technique, the suspension PS logging method, is described...
In-Place Permeability Measurement of Slurry Trench Cutoff Walls
A suggested procedure for the in-place measurement of slurry trench cutoff wall permeability is presented. The H. Bouwer and Rice method, employing a single observation well and variable-head...
In Situ Tests for Foundation Vibrations
There are several well established methods of determining shear modulus in situ and these are summarized in this paper. New techniques are being developed for in situ determination of...
N-Values Used to Predict Settlements of Piles in Egypt
A method is proposed for using the standard penetration N-values to predict the load-settlement curves for different piles used in Egyptian soils. The method is based on H. G. Poulos-E....
Initial Results From an In-Situ Consolidometer
An In-Situ Consolidation Evaluation Device (ICED) was developed for field measurement of consolidation parameters by electro-osmosis. A brief description of the test apparatus and the...
Comparison Between In-Situ Test Results
Penetration tests provide a means of obtaining data from which estimations can be made of the bearing capacity, settlement and liquefaction potential of the soils tested. Empirical formulae...
Use of Piezometer Cone Data
The piezometer cone is generally regarded as the most efficient tool for stratigraphic logging of soft soils. A thin pore pressure element (5 mm thick) can sense layers a few centimeters...
CPT Indexing of In Situ OCR in Clays
Cone penetration tests may be used to index the in situ preconsolidation pressure in clay deposits. A specified relationship between C//u/ sigma //vo and the overconsolidation ratio (OCR)...
Lateral Stress Measurement During Cone Penetration
A lateral stress sensing cone penetrometer (LSSCP) was designed and fabricated. Based on the results of calibration chamber tests in sand, relationships between measured lateral stress,...
The Pressuremeter for Foundations: French Experience
The paper presents historical information on the development of the pressuremeter and its application in the Laboratories Central des Ponts el Chaussees (LCPC). The continuous research...
Dilatometer to Compute Foundation Settlement
Sixteen examples demonstrate how the S. Marchetti dilatometer test (DMT) provides soil compressibility data for the rapid calculation of foundation settlements with an average ratio of...
In Situ Tests on a Florida Peat
A geotechnical exploration program at a site predominated by surface peats has been performed. The study encompasses the performance of in situ field tests and laboratory soil tests. Field...
Parking Lot Gets White Top
The many-acre parking lot at the Valley Fair Mall shopping center in Salt Lake City, Utah is described. In 1985 the asphalt pavement was overlaid with concrete, making it one of the relatively...
Permeability of Grouts Subjected to Chemicals
This paper presents the more recent results of a testing program which evaluated the long-term resistance to percolation of grouted soils, using acrylate, urethane and cement-bentonite...
Decreasing Clay's Permeability Using Aluminum Salts
The permeabilities of montmorillonite and kaolinite clays were reduced by precipitating aluminum hydroxide in the pores of the clay. The precipitate was formed by permeating the clays...
Design of Final Covers for Landfills
Final covers or caps are incorporated into a completed landfill to limit the amount of moisture percolation through waste materials. A properly designed final cover system provides the...
