- 摘要:
- 输变电工程跨度大，自然、社会经济条件及水土流失来源复杂多变，且临时占地多，扰动范围大。为探索输变电工程水土保持低扰动工程技术，为输变电主体工程及水土保持措施优化设计提供参考依据，以山西省18项500 kV输变电工程为研究样本，通过对比传统与低扰动的主体工程及水土保持工程实施的扰动程度和水土流失量，发现长短腿配高低基础的塔基和塔型设计、索道运输、不落地放线技术等低扰动技术应用于主体工程中能够显著缩小扰动范围、减少水土流失量；在水土保持措施设计中根据各防治分区的水土流失特点及土壤条件采用相应的表土剥离技术及在部分临时占地采用临时覆盖技术，则能减小水土保持工程的二次扰动，并且可以节省工程投资。建议在输变电主体工程及水土保持工程设计中，根据实际情况尽量优先采用这类有利于水土保持的低扰动工程技术。
- Abstract:
- Power transfer and transformation projects have the large span. So their natural conditions, social conditions, economic conditions and the source of soil and water loss are complex. Moreover, the projects temporarily cover large area and disturb a wide range. To explore the low disturbance engineering technology in soil and water conservation of power transmission construction and to help optimize the design of both the main work and soil and water conservation measures, eighteen 500 kV power transfer and transformation projects in Shanxi Province were selected as research samples. By comprising the extent of disturbances and the amount of soil and water losses caused by the traditional main work and soil and water conservation engineering and the low disturbance ones, it was found that the low disturbance engineering technology, including unequal legs and basis transmission tower,haulage methods of aerial cableway and actinobacillus without touching the ground, can significantly reduce the ranges of disturbance and the amount of soil and water loss. In the design of soil and water conservation measures, if the suitable surface soil stripping technology can be used based on the feature of soil and water loss and the soil condition in different control areas and temporary covering technology can be used in some temporary land, the secondary disturbance as well as the investments of the soil and water conservation engineering can be reduced. It was suggested that the low disturbance engineering technology which can reduce soil and water loss should be given priority in the design of main works as well as soil and water conservation measures of power transfer and transformation projects.
