| Abstract: | The dynamic design method is essentially the evolving processes of various information, it consists of dynamic design and information construction. It is a new technology of increasing popularity. Because of the particularity and complexity of the Qinghai-Tibet Railway construction, the technology of the dynamic design and information constructing was used tentatively. Based on processes of Qinghai-Tibet Railway construction, this paper discussed and analysed the idea of dynamic design and applications. Meanwhile in allusion to arisen problems in design and construction, some principles and suggestions of reinforced measurements were put forward. Though the works of construction and design are being carried through, good results have been obtained. |
