Abstract:: Based on samples of 220 kV and above power transmission engineering in Shanxi Province, low disturbance soil and water conservation technology integration is obtained by analyzing and evaluating foundation types, wiring installations, modes of transportation and prevention measures. The conclusions are as follow: the undisturbed soil foundation types, such as anchor arm, rock embedding and digging, bring less disturbing areas and cubic meters of earth and stone than heavy excavation foundation; the mode of unequal legs with unequal depth is the best combination in reducing disturbing areas and cubic meters of earth and stone; the technology of wire release without landing can reduce 50%～70% of disturb areas than convention wire release; by using cableway transportation, about 73%～92% of the disturbing areas can be reduced; the technologies of geotextile lying and revegetation can save 8% and 6.54% of soil and water conservation investment; low disturbance soil and water conservation technology integration can reduce 4.55%～34.42% of disturbing areas, 7.81%～25.86% of cubic meters of earth and stone, 0.59%～22.49% of construction investment and 1.83%～17.50% of total investment than traditional construction process.
