Uplift Capacity of Model Group Anchors in Sand
Small-scale laboratory experimental results for the ultimate uplift capacity of shallow horizontal circular single and group anchors embedded in sand have been presented. The experimental...
Identifying DepositionalAreas in Puget Sound
Depositional areas where fine sediments accumulate have been located through low-cost sediment studies instead of more costly current meter and settling trap measurements. Over 200 samples...
Chemical Effects on Clay Hydraulic Conductivity
Hydraulic conductivity and its susceptibility to changes with time or exposure to chemicals are major factors in selection of clay for use in waste containment barriers. Available concepts...
Effect of Rainfall Intensity Distribution on Excess Precipitation
The effect of the time distribution of rainfall intensity on the prediction of the depth of excess precipitation is evaluated. A comparison is made of the excess precipitation produced...
Use of SPT and CPT Tests for Evaluating the Liquefaction Resistance of Sands
A cone penetration test (CPT)-liquefaction resistance relationship has been established using the large body of standard penetration test (SPT) data. Factors for relating CPT tip resistance...
Flat Dilatometer Tests in Calibration Chambers
This paper presents the results of a series of Flat Marchetti's Dilatometer Tests (DMT's) performed in a large Calibration Chamber (CC) on dry Ticino (TS) and...
Cone Penetrometer Use on Uranium Mill Tailings
Piezocone data were found to be very reliable in the identification of uranium tailings according to the traditional categories of sands, sand-slime mixtures, and slimes by the use of...
Coupling Free Vortex Energy Dissipation with Sediment Control
The paper reports on studies showing that sediment control down to the abrasive limit of 30 micron sand and energy dissipation can be achieved simultaneously with a Teacup free vortex...
Soil Strength Determinations from the Cone Penetrometer Test
Geotechnical exploration in offshore Arctic regions often relies upon the electric Cone Penetrometer Test (CPT) because of its speed, economy, data continuity, and general reliability....
The Deformation Properties of Warm Underocean Permafrost
Two quasi-conventional incremental pressuremeter tests were carried out on man-made specimens of 'warm' ( minus 3 degree C) frozen, saturated sand. Instead of...
The Sand Mattress Method of Slope Protection
The sand mattress concept offers promise as an economical alternative to sand bag armor for two distinct applications: (1) slope protection for exploratory islands and/or causeway facilities,...
Geotechnical Characteristics of Seafloor Sediments: Norton Sound, Alaska
During the past few years the USGS has been conducting studies in the northern Bering Sea aimed at identifying geologic and environmental conditions that may be hazardous to offshore resource...
A Systematic Evaluation of Hillslope Subsurface Flow: The Effects of Slope Angle and Soil Parameter Variation
A two-dimensional finite element variably saturated flow model is used in conjunction with an automatic mesh generating scheme to simulate hillslope subsurface flow. Slopes from 2% to...
Examples of Sediment Distribution in the Italian Adriatic Coast. A Comparison Between the Shepard and the Nota Textural Classifications
Four sectors of the western Adriatic coast, each with a different feature, represent the test areas to evidence the differences between the two textural classifications of sediments by...
Experimental Study on Sandbag Stability and Runup
Sandbag model tests are performed in a wave flume to examine the effects of berm-type slopes on the stability of sandbags and wave runup as compared to uniform slopes. Measurements of...
Flint Tunnel?A Project of Change and Challenge
The talk will deal with construction of a 12' diameter (8. 5' finished) tunnel in the City of Flint, Michigan. This 5-mile long sewer tunnel was constructed through...
Time Rated Infiltrated Depth Families
A new set of infiltration families has been developed, for 'normal' soils to describe cumulative infiltrated depth versus time. This new family of curves is described...
Characteristics of Indiana Soil Properties
The Indiana Geotechnical Data Bank was established to collect engineering soil data in the state and to provide information for engineering planning and design works. It contains nearly...
Probabilistic Characterization of Nigerian Falls
A probabilistic method of subsurface characterization is developed for sites in Southern Nigeria. This method is based on the use of statistics to analyze real field data and determine...
Frost Action and Its Control
This state-of-the-art review addresses, in four separate papers, frost heave processes and their control. A review of the fundamental principles of soil freezing and thawing is presented...
