Space structures and Olympic gymnasiums

Shen Shizhao

Strategic Study of CAE 2008, Volume 10, Issue 8, Pages 12-21

Abstract:

Space structures are always preferred for Olympic stadiums and gymnasiums due to their great variety of forms, efficient mechanical behavior and the ability to cover large spans. The construction of 2008 Beijing Olympic stadiums and gymnasiums provides an enormous stage for space structures. It is advisable and useful for the further development of space structures to summarize the advanced design concepts, innovative structural forms as well as the new materials and techniques used in these stadiums and gymnasiums. A brief introduction to the 2008 Beijing Olympic stadiums and gymnasiums is presented first, then some representative Olympic stadiums and gymnasiums are discussed with respect to their novel architectural appearance, advanced structural forms and innovative techniques applied in design, construction and monitoring. By reviewing a number of classical Olympic stadiums and gymnasiums, their common characteristics are summarized as:perfect combination of novel architectural appearance, innovative structural form and satisfactory service performance;in accordance with the development of construction techniques, and hence promoting the progress of technology. Compared to the outstanding classical Olympic buildings, it is believed that some representative stadiums and gymnasiums of the 2008 Olympic Games do have the qualities to be recognized as the new members of this glorious list.

Control concept and countermeasures for shallow lakes' eutrophication in China

JIN Xiangcan, LU Shaoyong, HU Xiaozhen, JIANG Xia, WU Fengchang

Frontiers of Environmental Science & Engineering 2008, Volume 2, Issue 3, Pages 257-266 doi: 10.1007/s11783-008-0063-3

Abstract: Research on lake eutrophication in China began in the early 1970s, and many lakes in China are now known to be in meso-eutrophic status. Lake eutrophication has been showing a rapidly increasing trend since 2000. Investigations show that the main reasons for lake eutrophication include a fragile lake background environment, excessive nutrient loading into lakes, excessive human activities, ecological degeneration, weak environmental protection awareness, and lax lake management. Major mechanisms resulting from lake eutrophication include nutrient recycling imbalance, major changes in water chemistry (pH, oxygen, and carbon), lake ecosystem imbalance, and algal prevalence in lakes. Some concepts for controlling eutrophication should be persistently proposed, including lake catchment control, combination of pollutant source control with ecological restoration, protection of three important aspects (terrestrial ecology, lake coast zone, and submerged plant), and combination of lake management with regulation. Measures to control lake eutrophication should include pollution source control (i.e., optimize industrial structural adjustments in the lake catchment, reduce nitrogen and phosphorus emission amounts, and control endogenous pollution) and lake ecological restoration (i.e. establish a zone-lake buffer region and lakeside zone, protect regional vegetation, utilize hydrophytes in renovation technology); countermeasures for lake management should include implementing water quality management, identifying environmental and lake water goals, legislating and formulating laws and regulations to protect lakes, strengthening publicity and the education of people, increasing public awareness through participation in systems and mechanic innovations, establishing lake region management institutions, and ensuring implementation of governance and management measures.

Design concept of the Twin River Bridges in Chongqing, China

Man-Chung TANG

Frontiers of Structural and Civil Engineering 2011, Volume 5, Issue 4, Pages 427-431 doi: 10.1007/s11709-011-0134-6

Abstract: The Dongshuimen Bridge over the Yangtze River and the Qiansimen Bridge over the Jialing River in Chongqing, China are located at the tip of the Yuzhong Peninsula. Together, they are called the Twin River Bridges. Both are double deck structures carrying four lanes of traffic on their upper decks and two transit tracks on their lower decks. The girders are steel truss structures with orthotropic plates and the towers are made of concrete. Aesthetics were carefully considered for the design of these bridges because of their visibility in the city and their neighboring landmarks.

Chen Qingquan, Zheng Bin

Strategic Study of CAE 2019, Volume 21, Issue 3, Pages 70-75 doi: 10.15302/J-SSCAE-2019.03.017

Abstract:

New energy vehicles provide an important opportunity for the transformation and upgrading as well as high-quality development of China’s automobile industry. Based on the innovative thinking that should be maintained in the development of new energy vehicles, this paper analyzes the three elements required for innovation, i.e., ideas, talents, and atmosphere; it also presents the thinking methods required for innovation, i.e., prospective thinking, differential thinking, global thinking, and circular thinking. On this basis, it is proposed that the development of new energy vehicles should be promoted by innovation, policies, and the market; good products, infrastructure, and business models are crucial for the development; and the transport, energy, information, and cultural networks should be integrated. It is hoped that this study can provide strategic references for the development of new energy vehicles in China.
