| Abstract: | The distribution types and characteristics of permafrost along the Qinghai-Tibet Railway are described;and then the failure mechanism and harm of permafrost to ground and foundation engineering of transmission and transformation projects are expounded.The treatment method and design principle of foundations for transmission and transforming power projects in permafrost areas are also explored.Finally,some advises which can serve as reference for the design of transmission and transformation projects and foundation are proposed. |
