Remedial Design and Construction to Improve a Sliding Embankment
The paper describes the studies made to identify the nature of possible remedial measures such as improved drainage, removal of the weak clay layer or a provision of a buttressed dam....
Coolidge Dam Abutment Stability and Stabilization
This paper focuses on left abutment stability assessments and stabilization measures at Coolidge Dam, Arizona. Initial assessment of abutment stability was based on limited rock strength...
Using Innovative Technologies and Geosynthetics in Embankment Dam Rehabilitations
The ever increasing development and confidence in new and innovative technologies such as geosynthetics, in conjunction with often significant economic advantages, have led designers to...
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...
Soil Nailing Technique in Tunnel Support
Authors have developed a new pre-lining method (PASS method) in which thin archshell lining is formed ahead of the tunnel face before the excavation to reinforce the ground. This method...

Alternative Designs for Permanent Protection of the San Luis Rey River Aqueduct Crossings
The San Diego County water Authority was organized to provide an imported supply of water to the San Diego region. The sole source of the water to the Authority is Metropolitan Water District...
The Optimum Parameter Selection for 4-Point Time Domain Integration Schemes
In this paper, a general method of time dimension discretization based on the idea of finite element is presented for dynamic analysis. Two kinds of recurrent formulations are derived...
Application of PC Graphics, CADD, and Solid Modeling Techniques to 3-D Structural Stability of Concrete Monolithic Structures
A computer program for computing 3-D overturning and sliding stability (3DSAD) of concrete monolithic structures has been written and is widely used. This paper describes recent advances...
Expert System for the Preloading Method of Ground Improvement
Design practice of the preloading method, which is one of the ground improvement techniques, applied for the hydraulic fill area includes quite complicated problems, especially when draining...
Application of Spencer's Method for Slope Stability Analysis
For slope stability analysis with general, arbitrarily shaped failure surfaces, the Spencer's method has been found to provide a reasonably accurate result. This method satisfies both...
High-Tech Landfill Caps
Just as federal and state regulations detail every aspect of landfill location, construction and operation, they now detail every aspect of its design closure. A typical municipal solid...
Argentine Deltas Morphology
Only two deltas are located along the Argentine coast, both of them at Buenos Aires state. The northern one is the Parana Delta at the Rio de La Plata estuary (34.99' Lat. Sur) and the...
Streambank Inventory and Protection Soldotna Reach, Kenai River, Alaska
This paper discusses bank conditions found along the Kenai River within the city of Soldotna in Alaska. River banks were inventoried in May 1990 by USDA Soil Conservation Service (SCS)...
Plant Establishment Enhancement Technique for Shoreline Stabilization and Protection
Once established, vegetation is capable of significantly reducing erosion along streams, rivers, bays, sounds and other tidal shorelines. In the last 15 years, many attempts to establish...
