The research and practice of key technological issues in structure design of Three Gorges Project

Zheng Shouren,Niu Xinqiang

Strategic Study of CAE 2011, Volume 13, Issue 7,   Pages 20-27

Abstract:

The dam of Three Gorges Project is characterized by large flood discharge capacity, more outlets complicated flood discharge and energy dissipation structure etc., the gentle-dip structural plane of the bedrock in powerhouse dam section endangers the dam foundation stability due to the deep excavation of powerhouse at the dam-toe. For the dam body concrete, the durability requirement is high as well as the temperature control and crack prevention are difficult. There is a lack of practical experiences in the design and construction of asphalt concrete core wall for Maopingxi protective earth-rock dam. The power station operates with high water head and large head variation. The type selection of penstock and intake as well as the embedding way of spiral case are complicated in technique, and the tailrace tunnel with sloping ceiling of underground power plant is arranged instead of traditional tailrace surge tank. For the double-line five-step ship-lock, the design of fully lined ship-lock, high head delivery system and large-sized miter gates and hoists is very difficult due to high operation head, complicated delivery conditions and building in deep excavated rock. The preferred solutions, optimal schemes and technical measures for various structures, as well as the innovation achievements proved by practice are highlighted.

Regulatory issues for genetically modified animals

Perry Bradbury HACKETT

Frontiers of Agricultural Science and Engineering 2020, Volume 7, Issue 2,   Pages 188-203 doi: 10.15302/J-FASE-2019307

Abstract:

Precision genetics and breeding have the potential to meet the agricultural needs and goals of the world in the 21st century. These needs include increasing the efficiency of production of animals and improving their products with minimal impact on the environment. The USA is the major innovator in genomic science and the acknowledged leader in formulating policies to regulate genetic applications in medicine and agriculture. However, governments worldwide have been exceedingly reluctant to support the introduction of genetically modified (GM) animals into agriculture. Regulatory policies have stagnated due to legal guidelines that could not anticipate the needs and solutions that are evident today. This must change if we are to maintain planetary integrity. I propose a new, market-based regulatory model for GM livestock that has both a strong scientific foundation and has worked for 10000 years. The model is similar to that for information technology in which specific algorithms drive computer and cell phone applications. Genome engineers write genetic algorithms that drive the traits in biological organisms. Accordingly, GM products should be viewed in terms of their use and public benefit rather than by limitations to the genetic programing coming from a few highly vocal groups. Genetic algorithms (Genapps) of the 21st century will include not only introduction of synthetic genes, but also complete natural and synthetic biochemical pathways to produce agricultural products that are maximally efficient, healthy to humans and animals, and sustainable in an era of changing climates while avoiding environmental degradation.

Several issues to be considered for long-term better behavior of concrete gravity dams

Jinsheng JIA,

Frontiers of Structural and Civil Engineering 2010, Volume 4, Issue 1,   Pages 40-46 doi: 10.1007/s11709-010-0006-5

Abstract: Along with economic, social quick development and urbanization, dams and reservoirs are of strategic importance for flood control, water supply, electricity production, irrigation, etc., both for developed countries and for developing countries. Climate change is a new challenging issue to be considered which will speed up the development of hydropower in developing countries. More and more attention will be paid on the long-term better behavior of dams to guarantee the safety of the people involved and the better development of the world. There are about 50000 old dams in the world and a lot of them have been completed and operated for more than 50 years. However, how do we evaluate the dams’ safety? How do we make the decision to do rehabilitation work or to rebuild a new dam based on evaluation results? The life span and the real safety status of old dams becomes a challenging task for the dam society, especially for China because it has more than 6000 dams to be evaluated and rehabilitated within the next few years. Based on the investigation of the Fengman gravity dam, which is 91.7 m high, operated since 1943 and suffered uplift pressure, freeze and thaw problems, etc., discussions on the life span evaluation of old concrete gravity dams have been made. The reasonable coefficient of dam safety has been discussed. The social decision for the final choice after comprehensive studies has been introduced.
