Tour 3:  Guangzhou city-Dongyang Project (under construction)-Qianwei Project (completed)-Chengdu city

Dongyang Project is located in Qingchuan County, Sichuan Province. The normal water storage level is 932 m, the normal storage capacity is 5.32 million m3,and the total storage capacity is 7.17 million m³. The project consists of a hub project and an irrigation area project with multi-purposes such as agricultural irrigation and rural water supply. The dam of the hub project is a cemented sand-gravel-rock dam(CSGRD), with a crest length of 135.5m, a crest width of 6m, and a maximum dam height of 66.5m. The cross-section of the dam is a trapezoidal section, with an upstream slope of 1:0.4 and a downstream slope of 1:0.7. The construction of dam officially started in May 2022 and is scheduled to be completed in 2024.

Qianwei Project is located in the downstream section of the Minjiang River in Sichuan, with a total storage capacity of 227 million m3 and a total installed capacity of 500MW. The project development is mainly focused on shipping, combined with power generation, water supply and irrigation. The protection project is an important component of the Qianwei Hub. The material of levee in Tangba village adopted cemented sand-gravel-rock. The axis of the levee is about 2.71km long, the crest elevation is 336.1m, the elevation of the top of the wave wall is 337.3m, the width of the embankment top is 5m, and the minimum elevation of the foundation surface is 323.2m, and the maximum height of the dam is 14.1 m. In 2020, it successfully withstood the test of overtopping.

Symposium Program

Spanish National Committee on Large Dams (SPANCOLD), Japan Commission on Large Dams (JCOLD), French Committee on Large Dams (CFBR) and Chinese National Committee on Large Dams (CHINCOLD) have the honor to invite professionals to the 9th International Symposium on Roller Compacted Concrete (RCC) Dams and Cemented Material Dams, which will be held in Dec.4th-8th,2023 in Guangzhou City, China.

RCC dams have the virtues of saving a great deal of concrete, building quickly, making project cost down and early bringing into playing project advantages and so on. Hence, the technique of constructing dams has been quickly spread and applied since it came out. Today there are more than 400 RCC dams in more than 40 countries. Great successful experiences and advanced technologies have been achieved. CHINCOLD and SPANCOLD have devoted to promote the technology from early 1990’s. The first Symposium on RCC dams was jointly organized by the two committees in 1991 in Beijing China, which was a success start of the series of RCC Symposiums.

Cemented Material Dam (CMD) is a new type of dams, which includes Hardfill dam, Cemented Sand and Gravel dam (CSG), Cemented Sand, Gravel and Rock dam (CSGR), Rock-filled Concrete dam (RCD), Cemented Soil dam (CSD), and so on. There are more than 200 CMD projects constructed and under construction.

The 9th International Symposium on Roller Compacted Concrete (RCC) Dams and Cemented Material Dams will provide a platform for practitioners, engineers, researchers, scientists, managers and decision makers from all over the world to exchange ideas and technology about the latest developments dealing with RCC dams and CMDs. Beside international best practice, the participants will also have the occasion to visit some famous RCC dams and CMDs in China in operation or under construction.
