Quarry Techniques for Dimensional Breakwater Stone
On the Texas Gulf Coast, there has evolved a unique design for breakwater and jetty structures. The Galveston District of the U.S. Army Corps of Engineers, the designer of these structures,...
Quarry Inspection: A Geological Perspective
The need to use durable rock in building projects is becoming more critical as the costs of labor and materials rise. The Steering Committee of the 1991 Quarried Rock For Rubble Mound...
Producing Armourstone Within Aggregate Quarries
This paper discusses a series of full-scale trial blasts which was conducted in an aggregate producing quarry with the objective of improving yields of armourstone. The quantitative research...
Some Case Histories of Armor Stone Production
The blasting techniques used to produce armor stone, derrick stone, and underlayer stone [one to twenty tons] for the construction of rubblemound breakwalls and the confined Dike Disposal...
Recent Experience With Armor Stone Cracking in the Buffalo District
Accelerated deterioration of large armor stone on the Cleveland East Breakwater, Cleveland, Ohio has resulted in the need for more intensive monitoring of the entire armor stone production...
The 1984 Major Rehab of the Muskegon Harbor, MI South Breakwater: An Extreme Example of Misguided Design of a Stone Structure
It can be inferred from the Shore Protection Manual that the stability of any coastal structure is increased in proportion to the weights of the armorstones. The south breakwater at Muskegon...
The Durability of Rubble Mound Armour in Service ? A Case Study
Over the past decade, the ongoing monitoring of Gold Coast rubble mound structures in service has demonstrated a serious loss of durability over a period of time in the rock units after...
The Optimum Gravity Dam
A method is presented for optimizing the cost of a dam by varying the properties of the material and the shape of the dam to produce the lowest cost water barrier to perform the required...
RCC for Rehabilitation of Dams in the USA-An Overview
The use of roller-compacted concrete (RCC) has rapidly become a powerful new tool in the USA for engineers involved with the rehabilitation of existing dams. Starting in 1980, RCC has...
Design and Proposed Construction Techniques for Pangue Dam
The paper describes the site conditions, design and proposed construction methods for the 115 m high Pangue Dam, Chile's first RCC dam. Trial mix design work and test embankments...
The Construction of New Victoria Dam, Australia
The paper discusses various aspects of the construction of the New Victoria Dam, a 52 m high, high-paste content RCC dam constructed near Perth, Western Australia. The mix design and its...
Design of Miel II?A High RCC Dam
Miel II Dam is a 141 m high RCC structure designed for the tropical mountains of central Columbia. Interesting features are its height (considerably higher than any existing RCC Dam),...
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...
The Design and Construction of Shuikou Project RCC Diversion Wall
Shuikou Hydroelectric Project, currently under construction on the Minjiang River in the People's Republic of China is a concrete gravity dam having a maximum height of 101...
A Review of Design Criteria for High RCC Dams
The 1980s could be considered to be the decade during which roller-compacted concrete dams came of age. This economic method of construction is sufficiently proven that very large dams...
Performance of Upper Stillwater Dam
Upper Stillwater Dam was constructed with roller compacted concrete (RCC) and horizontally slipformed facing. This unique construction method for a concrete gravity dam included no contraction...
Lessons Learned from Elk Creek Dam
This is the third of a series of papers published on the design and construction of Elk Creek Dam. The first paper discussed design and construction concepts to provide water tightness...
Roller Compacted Concrete Tailing Retention Dam
A roller compacted concrete (RCC) dam has been designed for gold tailing impoundment in southeast Alaska. To minimize up front capital costs, the curved gravity dam with multiple outlet...
Concepcion Dam Design & Construction Problems and Their Solutions
Concepcion Dam is a curved axis gravity structure 68 m high and 695 m long. It supplies water to Tegucigalpa, the capital of Honduras. The dam contains 290,000 cubic meters of RCC. Challenges...
RCC Dam Construction?A Contractor's View
