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...

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...

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...

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...

The Role of Shale Pores in Settlement
Waste fills resulting from the mining of coal in Appalachia should ideally consist of large, free-draining sedimentary rock fragments. The successful performance of these embankments is...

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...

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...

Probabilistic Observation Method for Settlement-Based Design of a Landfill Cover
Uncertainties in subsurface conditions make predicting total and differential settlement a difficult task. The Observation Method, which is commonly implemented to acquire additional knowledge...

On the Erodibility of Rock and Other Earth Materials
An outline of a new method to determine the erodibility of rock and other earth and engineered earth material is presented. The method quantifies the relative capacity of the boundary...

Influence of a Sand Layer on Headcut Advance
The presence of an erodible material layer in the soil profile has been observed to influence headcut movement in earth emergency spillways. Large-scale flume tests were conducted to examine...

Banking on a Bridge
Completing the geotechnical design for the approach embankments and foundations for the Charter Oak Bridge, which crosses the Connecticut River between Hartford and East Hartford, Conn.,...

Stability of Embankments, Fills and Structures at the Bad Creek Project Under Static and Dynamic Loading
Duke Power was faced with the problem of using explosives to assist in removing a sensitive, saturated embankment cofferdam supported on a large rock plug. The first phase of the work...

Seismic Safety Modification of an Old Earthfill Dam
Chollas Dam was built as a water supply reservoir for the City of San Diego. The reservoir is no longer a part of the municipal water system but has been operated since 1966 as a recreational...

Numerically Predicting Horizontally Oriented Spent Fuel Rod Surface Temperatures
A comparison between numerical calculations with use of commercial thermal analysis software packages and experimental data simulating a horizontally oriented spent fuel rod array was...
