摘　　要：玉树与青海主网330kV线路工程沿线年平均地温高、水系发育,造成冻土的类型、分布格局等都复杂多变,为了解决线路中路径的合理选择及优化、适宜的基础型式应用等,开展了沿线的冻土研究,其结果合理指导了路径及基础型式的优化与选择,规避了线路中的不良冻土工程地质问题,对工程的顺利实施具有较大的经济价值。＂330kV Transmission Line of Main Power grid in Yushu and Qinghai Project＂ . has high annual mean ground temperature and intricate water system, the type and distribution of frozen soil is complicated along the project. The purpose of the study is to select a logical line path, and to optimize foundation design. It has guided the selection and optimization of line path and foundation type, and has avoided the harmful geological problems of permafrost, and will have a great economic value for the smooth implementation of the project, by our study.
