摘要
中国21世纪的跨海工程将面临软土地基、强台风、深水基础等条件,仅用悬索桥和斜拉桥作为大跨桥型,已不能满足工程需求。作者建议采用斜拉-悬吊协作体系以及多跨索支承组合体系来取长补短,弥补体系之不足。本文以伶仃洋大桥工程为背景,探索了1400m伶仃东航道斜拉-悬吊协作体系的设计,为这种桥型的设计和跨世纪、跨海大桥方案研究提供参考依据。
The 21st century project of a strait crossing is faced with much natural conditions such as the soft foundation, the violent typhoon, and the deep - watered foundation. Only to take a suspension bridge or a cable-stayed bridge as a long- span bridge type is not satisfied with the engineering requirements. The cable - stayed suspension bridge and multi - span cable - supported combined system can make up the deficiencies. A design of the cable - stayed suspension bridge of 1400 meters is Proposed in the paper. It is assumed locating on the east channel of the Lingding strait.
