The artificial intelligence, optimization methods and CAD techniques are mixed to develop an integrated system for design of arch dams. It includes a knowledge base, a data base, a stress...

A Study on Aseismic Behaviours of Composite Trussed Arch Bridge
Composite trussed arch bridge is a new type bridge structure developed in China recently, It has the following features: good integrality, reasonable inner force distribution, great spanning...

Nonlinear Trial Load Method of Arch Dams
The trial load method is still an important method for the stress analysis of arch dams at present. However, the trial load method can be used only for the linear elastic analysis of arch...

Rive, Rive-Grown and Burst Probability of Rolled Compressive Concrete Arch Dam
The rive, every step of the rive grown and even burst of arch dam are regarded as sequence random events. Making use of the probability theory and the achievement of elastic, elastic-plastic...

The Application of Gauss Numerical Integration Method in Arch Dam Trial-load Method Program
The characteristics of Gauss Numerical Integration Method are the unequal distance between nodes and fairly high accuracy. When the number of nodes is n, the algebraic accuracy can be...

Analysis of Cabinet Gorge Dam
After a 1987 inspection of the Cabinet Gorge Dam, Part 12 consultants contracted by Washington Water Power (a private utility based in Spokane, Washington) made several recommendations...

Dam Safety Modifications for Clear Creek Dam Manuscript for ASCE Hydraulics Division 1993 National Conference on Hydraulic Engineering
Clear Creek Dam, an unsafe thin arch dam, was stabilized by constructing a concrete gravity buttress on the downstream face. During the Bureau of Reclamation's (Reclamation) Safety Evaluation...

Concrete Arch Bridges Using Composite Techniques
Use of composite structure is an advantageous method to construct concrete arch bridges. This paper reports two successful examples of concrete arch bridges of composite construction using...

Arches For A Parkway
The final phase of construction on the Natchez Trace Parkway (which follows a centuries-old 450 mi trail between Natchez, Miss. and Nashville, Tenn.) is nearing completion almost 60 years...

Roller Compacted Concrete Arch/Gravity Dams?South African Experience
The paper traces the development of roller compacted concrete (RCC) dams in South Africa, and in particular the application to arch/gravity dams. The Department of Water Affairs and Forestry...

Final Design and Construction of Gibraltar Dam Strengthening
The results of a 1983 safety evaluation of Gibraltar Dam indicated that the dam did not meet seismic safety standards. A remedial scheme involving the addition of a roller compacted concrete...

Santa Cruz Dam Modification
Santa Cruz Dam was the first concrete arch dam in the United States to be modified using an roller compacted concrete (RCC) buttress. Innovative techniques included forming the stepped...

Designing Reinforced Rock
The reinforced rock arch design method has been used to stabilize coal mine excavations for 40 years, but so far has been applied to only a few tunnels. The use of rock reinforcement develops...

Response of Suspension and Deck Arch Bridges to Spatially Varying Ground Motion
Recent awareness of the spatial variation of earthquake ground motion has caused concern about the safety of large engineered structures under seismic excitation. The effects of spatially...
