In the view of the application and extension of angle steel lean-inserting foundation in the transmission line construction,the calculation of position、constructive control and measurement system about angle steel lean-inserting foundation used in the direct current transmission line construction of ±500kV Yangtse gorges-Guangdon are introdued.

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

Based on the summarization about deficiencies in traditional way calculating and controlling slope of embedded inclined-angle-iron with plummet,a new method on using theodolite was introduced.
