Pullout ture experiment on the inserted foundation;

Along with the further progress of the West Development, and wide application of the latticed steel tubular tower, double circuits on same tower and many circuits on same tower in UHV transmission lines, inserted foundation also got the extensive application, but theoretical study is a long way behind engineering practice.

Experimental research on load bearing capacity of stub-angle-inserted foundation for 750 kV transmission line tower;

Discussion on iron tower foundation style choice

The part area adopts heat-bar treatment measure,to ensure permafrost areas iron tower foundation s stability of Nachitai-Wudaoliang-Tuotuohe transmission line engineering.

The optimum design of independent iron tower foundation with the method of network searching is studied.

Through calculation and analysis,as well as many years\' operation practice it is a reliable way that slope value of mountainous HV transmission tower foundation calculated based on rock shearing area is reduced by 1 m,the foundation depth should be added by 0.

Based on technologies related to tower foundation design in mining areas and foundation stability evaluation,as well as quantified analysis and comparisons of distortion of every foundation,with goals of safe,reliable,and economically sound,principles of tower foundation design,feasible foundation types and design schemes are determined to ensure safe and reliable operation of the line.
