Design Proposal for Luyang Sea Crossing in Phase I Project of Yang Shan Deepwater Port Chapter XIIChapter XIIAesthetic Design12.1 BriefShanghai, situated in the middle of Chuang Jiang, Dung Hai, Hang Zhou bay, is the potential port for future economic development. Hence, a deep harbour is necessary to be constructed such that big ships can enter and makes Shanghai as an internationally transport and transit centre. The construction of the Lu Yang Bridge can solve the cargo transport problem between Hong Kong and Mainland China and inner city and outer islands. It can also easily resolve the supply of water, electricity and telecommunication systems between Hong Kong and the Mainland. The associated advantages include the potential rise in value of land adjacent to the Bridge and Lu Chao Harbour city will also be developed as well following the development of Yang Shan Deepwater Port area. The development of Lu Chao Harbour city will lead to development of the whole Po Dung area.12.2 Bridge Aesthetic DesignThe surrounding to the port is open and spacious with the unique ocean view which extends to far horizons. Hence, the huge Bridge structure will standout and become the local viewpoint, therefore the aesthetic design appearance is crucial.The bridge design nowadays not only must satisfy its functional purposes and outlook including the long span, strong physical appearance but also higher expectations from the cultural, geological side etc. Therefore, it is necessary to satisfy its functional purposes as well as the regional background, technological, economical and aesthetic issues.To gain economies of scales, Lu Yang Bridge should incorporate artistic and technological advancement. Hence in the Bridge design, we have to give the Bridge a unique cultural appearance which enhances the locals feelings and reflect our creativity.12.3 Environmental Design1. Natural EnvironmentShanghai is close to the Chuang Jiang delta with East China Sea in the East, Hang Zhou Bay in the South, Tiang-su/Zhe-jiang in the West and Chuang Jiang in the North. It is situated in the middle of the North-South Coastal Line where transportation is easy, land is spacious and is located in a geographically sound port area. Within the region of Shanghai, there are lots of low leveled plains. Shanghai belongs to the plains of Chuang Jiang delta, with an average sea datum level of approximately 4m. Hang Zhou bay is the biggest trumpet shaped harbour, with an average 8 10m sea level. The bottom sea level is flat, the harbour starts nearby Han Pu with a width of 20 kilomiles and ends at area from mouth of Nai-Hui, Shanghai to Zhen Hai of Ning Bo with a width of approximately 100 kilomiles. Within the harbour, there are lots of coral reef which is the unique attraction of the port.The site for constructing the Lu Yang Bridge is formed by sand fill, and it is currently surrounded by the harbour and subjected to tidal effects. The G1 area to the Bridge is used as a fish pond, G1-G3 area is used as a planting pond and G3 to area at height 1.0m is the beach. The Bridge is located in the flat part of the sea at water depths of 5 12 m. 2. Human DevelopmentThere is already human existence with great inventions in the area as early as more than 5000 years ago at the Stone Age. And there is also “Wu Yue Culture”, once ruling the region, origining from the site during Chun-Qiu Zhan-Guo Period. Today, Shanghai becomes the most prominent city with great historical treasures and strong cultural background. It is the most treasured city with few thousand years of history and different resources. During Nan Song Period, southward transference of royalty felicitates the blending of southern and northern culture and arts. Tang Poem, Song Expression, Yuan Song , Ming and Qing legend and other culture developed completely during this period, some of them even formed specific cultural character of grace and purity, modesty and tranquility. Mr. Lu Xun, a well-known writer of Modern China, once said, historic culture benefits mankind most in rebuilding humanity and molding personality. Therefore, the combination of cultural sight with bridge design can be lifted to a height of spiritual and civilized process, seeking unification of material substance and spiritual connotation in syndrome differentiation. From ancient time to present, bridge, with its unique charm, has always been associated with urban image: The romantic “Galaxy Bridge” for Wu Gang and Chang E, Lu Gou Bridge, which witnessed historic vicissitude and modern bridges reflecting scientific and technological progress of China. Bridges endowed with culture bear outstanding vitality, which proofs that only tight combination of humanistic and cultural sight with bridge design can produce scene of “Vitality and Connotation”.12.4 Creat
