以北京市的10个大中型输变电工程为例,对输变电工程建设期的水土流失进行了分析,结果为:变电站区、施工便道区和塔基区是输变电工程产生水土流失的重要区域,分别占水土流失总量的40.03%、17.18%和14.42%。针对输变电工程产生水土流失的重点区域提出了相应的防治措施:变电站区除了要进行土地整治外,更应重视雨洪利用措施的布设;塔基区除了要做好边坡防护外,还要处理好余土余渣;施工便道区要注意排水工程的设计和植物措施的布设。
Taking 10 medium and large power transmission and transformation projects in Beijing as an example, the soil and water loss during the construction period of power transmission and transformation project are analyzed. The results are as follows: Substation area, construction access road area and Taki district are the soil and water loss Of the major areas, accounting for 40.03%, 17.18% and 14.42% of the total soil erosion respectively. In view of the key areas of soil and water loss caused by power transmission and transformation projects, the corresponding prevention and control measures are put forward. In addition to the land remediation in substation area, more attention should be paid to the layout of rainwater utilization measures. In addition to slope protection, To handle the surplus soil residue; construction pavement area should pay attention to drainage design and plant layout.
