高速公路建设区的水土流失与防治技术

以辽宁省盘海（盘锦至海城）高速公路建设为典型，系统地分析了高速公路建设区水土流失发生发展的成因和形式；利用水土流失预测数学模型对可能造成的水土流失量进行了估算；运用工程力学和水土保持生态环境治理的基本理论，研究提出了稳固（定）创面和土体挡土墙工程，工程与植物措施相集成的三维植被圊土网垫技术，以及人工整地与植被恢复造田利用工程等水土保持措施，可为高速公路建设区的水土保持生态环境建设及其周边地区环境资源的开发利用提供科学依据。

Soil and water loss and its prevention and control techniques on highway construction area

By choosing the pan-hai(Panjin city to Haicheng city) highway of Liaoning province as the experimental site, the cause of formation of the soil and water loss and its happening form were analysed systematically. The potential soil erosion amount was estimated with soil and water loss prediction models. Following engineering mechanics principle and soil and water conservation theory, the comprehensive control measures of soil erosion were put forward, which included the terrace wall projects of stabilizing the ravaged section and soil mass, the three-dimensional vegetation network fixation soil techniques, soil preparation for afforestation, vegetation restoration and utilization projects, and so on. This study can provide scientific basis for soil and water conservation and ecological environment control, and its resources use in the highway construction area.
