21世纪初中国重大工程建设中的若干机械强度问题

SOME MECHANICAL STRENGTH ISSUES IN CHINESE KEY ENGINEERING BUILDINGS AT THE BEGINNING OF 21ST CENTURY

就与结构安全性可靠性有关的近期重大建设工程和近二十年来国内外发生的由于结构强度和振动问题引发的重大事故进行综述。提出重大建设工程中的若干机械强度与振动问题。这些工程项目是喷气式民航飞机、长寿命高可靠性通信卫星、100万千瓦核电站、提速铁路、磁悬浮铁路、西气东输工程和巨型水电站。最后讨论应予考虑的几个问题。

The catastrophic accidents caused from structure strength and vibration are described at home and abroad in the recent two decades, and listed the Chinese key engineering biddings related the structure reliability and safety at the beginning of 21st century. Some mechanical strength issues of the key engineering biddings in China are presented. These engineering projects are: civil jet aircraft; long life and high reliability communication satellite; 1000 MW nuclear power station; quasi- high speed railway; magnetic suspension railway; Xingjiang-Shanghai gas pipeline building engineering; large scale hydropower station. Lastly, it is also discussed some ideas must be considered.
