The analysis for application of rock foundation in mountain area;

Through analyzing and discussing some of tower rock foundations which is in common domestic are at present,according to surface features of poly-mountain and hill in Jiangxi,a new type rock foundation is designed and applied in connecting the Hubei to Jiangxi power network engineering of 500kV transmission line.

In connection with the characteristics of Yichang mountain area,the key method to reduce the cost and time of transmission lines construction and to make the operation convenient is applying large number of rock foundations.

During a 500 kV line embedded rock foundation full scale test in Hunan Province,foundation load bearing characteristics and failure mechanisms are analyzed based on test data.

Researches on pull-out capacity calculating method of rock bolt foundation

The experiment and application studies of rock bolt foundation in North China area in 2005 indicated that it is feasible to use rock bolt foundation in North China s strong weathered rock foundations.

Based on the experiment study project of rock bolt foundation in North China and its application in Hun-BaLine and Shang-Chen Line construction, this paper discusses technique of rock bolt foundation construction in strong and medium weathered rocks, such as granite, gneiss and limestone.

Field prototype tests about the rock embedded foundation have been carried out for a 750 kV electric power transmission line in Gansu Province.
