Grout Supports Brooklyn Tunneling
At the Red Hook project in Brooklyn, microfine cement grout was injected from the surface to support underground tunneling. The hand-dug tunnel was built to connect to sewer pipes. Subsurface...
Planning, Design and Cost Estimates for RCC Dams
Engineers, planners, and officials of agencies responsible for developing water resource projects are confronted with preparing preliminary designs and cost estimates for dams. This paper...
Behavior of Completed RCC Dams
Enough roller compacted concrete dams have been completed to allow an overall evaluation of this new approach to construction. Performance has been good. No operational restrictions have...
Comparison of Joint Shear Strengths for Conventional and Roller Compacted Concrete
Direct shear test data for parent material and bonded and unbonded jointed specimens of conventional and RCC (roller compacted concrete) are presented and compared. Results are discussed...
Roller Compacted Concrete Mix Design for Pamo Dam
Pamo Dam is designed as a 265 foot (81M) high gravity dam that will be located on the Santa Isabel Creek in San Diego County, California. RCC volume will be approximately 491,000 cubic...
Monksville Dam: Design Evolution and Construction
This paper documents the application of experience gained at other RCC projects to the Monskville Dam. The evolution of the design and its translation to construction are presented together...
Quality of Works in RCC in France: A Contractor's Solution
Bec Freres S. A. , a French dam contractor, introduced the technique of roller compacted concrete (RCC) into France. The first two French RCC dams were built as a result of a program of...
RCC in Dams in Australia
The design, construction and performance of the first three dams constructed in Australia, using RCC are described. Aspects covered in the paper include designing for zero cohesion between...
Vibration Analysis Using a Parallel Lanczos Method
A parallel eigenvalue solution algorithm, based on the Lanczos method, has been developed, implemented on a Flexible Computer FLEX/32 multi-processor, and applied to an example structural...
Concurrent Nullspace Methods for Multibody Systems
This paper presents a new concurrent multiprocessing algorithm for simulating the dynamics of constrained multibody systems. The systems considered are quite general in nature; they may...
Parallel Algorithms for Structural Optimization Under Dynamic Loading
Parallel algorithms and strategies are outlined for optimal design of frame structures subjected to dynamic earthquake loading. Parallelism is extracted in six areas: substructuring of...
Structural Analysis and Parallel Computers
This paper discusses the implementation of a parallel program that performs a two dimensional rigid frame analysis on a NCUBE/7 hypercube multicomputer. The program was written in C and...
A Finite Element System for the CDC CYBER 205
This paper summarizes some of the special considerations required for finite element system development on the CDC CYBER 205. A means of constructing an efficient database is presented....
Finite Strip Method in a Parallel Computing Environment
The finite strip method has been used to model many systems in structural mechanics. The orthogonality of appropriately selected shape functions allows a continuous system to be effectively...
Pull-Out Response of Geotextiles and Geogrids (Synthesis of Available Experimental Data)
During the past 15 years, there has been a considerable growth in the use of various materials to reinforce soils. The rapid development of geosynthetics and their increasing use in soil...
Laboratory Study of Geogrid Reinforced Soil Walls
The paper describes the construction and testing of three (3) large-scale geogrid reinforced soil retaining wall models. The models were 3 m high and were built in the RMC Retaining Wall...
Controlled Yielding of the Lateral Boundaries of Soil Retaining Structures
Lateral expansion of conventional or reinforced soil backfills is necessary to establish and maintain the minimum lateral stresses on soil retaining structures. Laboratory studies are...
Coal Mine Subsidence and Structures
Underground coal mining has occurred beneath 32 multiplied by 10**9m**2 (8 million acres) of land in the United States and will eventually extend beneath 162 multiplied by 10**9m**2 (40...
Mining Subsidence Effects on Transportation Facilities
This paper presents case history information about mining subsidence effects on transportation facilities, including bridges, pavements, and culverts. Most of the field observations pertain...
Mechanisms of Subsidence Induced Damage and Techniques for Analysis
Structural damage due to mining induced subsidence is a function of the nature of the structure and its position on the subsidence profile. A point on the profile may be in the tensile...
