1、 公路边生态工程高品质呈现应该从哪方面入手在公路边坡的养护管理工作中,一般分为工程防护和植物防护。工程防护一般多为钢筋、水泥组成的刚性防护,而植物防护则是柔性防护。边坡植物防护的主要目的是固土护坡、防止冲刷,兼有美化环境的功能。In the slope of highway maintenance and management work, usually divided into engineering protection and vegetation protection. Engineering protection for the general rigid protection of

2、 reinforced, cement composition, and plant protection is flexible protection. The main purpose of slope vegetation protection is soil slope, prevent erosion, has the function of beautifying the environment.边坡养护管理是公路养护管理工作的重要构成内容之一,直接关系到车辆的行驶效率及安全关系较大。特别是在我国西南部,雨水天气较多,受雨水冲刷、温差以及湿度变化的影响,容易产生边坡坡面岩石风化病害

3、、崩塌、滑坡以及泥石流等。因此,积极应用现代养护技术提高边坡养护质量,对保障现代公路交通运输安全有着重要的现实意义。Slope maintenance management is one of the important contents of the highway maintenance management, directly related to the vehicle efficiency and safety. Especially in Southwest China, more rain, washed by rain, temperature and humidity cha

4、nge, easy to produce slope rock weathering damage, collapse, landslide and debris flow. Therefore, to improve the quality of modern active application of slope maintenance maintenance technology, has important practical significance to guarantee the modern highway transportation safety.在公路边坡植被防护工作中,

5、首先应做好生态环境条件分析,即:在植被恢复与重建场所,与植被生长和发育有关的所有环境因素的综合。一般影响植被生长的立地条件包括气候、地形、土壤、水文与植被条件等。但与其他种类的造林地(或退化生态系统)相比,公路边坡植被生态重建的环境问题特殊性主要是:地表组成物质有机质含量少,物理结构极差,尤其是保水、持水、保肥能力差;存在限制植物生长的物质;土壤生物缺乏,尤其缺乏对植物生长有利的动物,如蚯蚓、线虫及微生物等方面。In slope vegetation protection work of highway, should first do a good job of ecological env

6、ironment condition analysis, namely: in the place of vegetation recovery and reconstruction, and all the factors related to the vegetation growth and development. Site conditions generally effect of vegetation growth include climate, topography, soil, hydrology and vegetation conditions. But with ot

7、her species of plantation (or degraded ecosystem), environment problems of highway slope vegetation ecological reconstruction special is mainly: the surface composition of the material of organic matter content, the physical structure is very poor, especially the water retention, water retention, fe

8、rtilizer retention ability is poor; the limitation of plant growth substances; soil biological deficiency, especially the lack of good animal growth of plants, such as earthworms, nematodes and microbes etc.由于公路边坡往往比较陡,为了使绿化的景观优美、方便栽植工程施工和树木的栽植,需要对边坡进行整形。具体在整形时需要考虑,建立一条环山小路直达边坡最高处,便于运料和整地施工;结合景观设计和整

9、地种植,采取平缓陡坡等方法重塑地貌景观;建立排水系统:在坡度较大的边坡,容易发生表面侵蚀,产生水土流失,特别是夏季常有暴雨,边坡积水面积很大,雨水汇集到一起后,很容易冲刷覆盖在表面的松土,甚至产生大量的侵蚀沟。因此整形的同时应设计完善的排水系统。Due to the highway slope is steep, in order to make the landscape planting beautiful, convenient construction and planting trees, the need for plastic on the slope. Concrete in

10、plastic needs to consider, to set up a mountain road to slope top, easy to transport material and preparation of construction; combination of landscape design and preparation of planting, adopts the method of gentle slopes to reshape the landscape; building drainage system: on steep slope, prone to

11、surface erosion, soil erosion, especially rainstorm often in summer, large slope water, rainwater collection together, it is easy to scour covers the surface of the soil, and even erosion gully large. Therefore, shaping and drainage system design.为了改善边坡的立地条件,防止遇到大风和雨水时造成径流和侵蚀,创造植物生长的有利条件,同时也为边坡的植被恢复

12、工程的施工安全和方便,整地是十分必要的。按照既经济省工又能较大程度改善立地质量的原则,对边坡采用局部整地方式。在矿车局部整地方式中,带状整地方法和块状整地方法均可采用。为汇集降水促进植物生长,认为反坡带状的方法是最可取的方法,边坡整地时要考虑整地的深度、宽度、长度、断面形式等因素。In order to site conditions improve slope, prevent runoff and erosion caused by the wind and rain, and create favorable conditions for the growth of plants, bu

13、t also to restore security and convenient construction for slope vegetation, soil preparation is necessary. According to both the economy can greatly improve labor and site quality principles, local soil on slope by means of. In the local soil preparation, preparation method and preparation method o

14、f strip block can be used. To bring together the precipitation to promote plant growth, and that the method of reverse slope belt is the most desirable method, slope tillage should be considered when ploughing depth, width, length, cross section form factors. 高速公路边坡植物种类的选择遵循以下原则:一是以乡土树种为主。乡土树种是在长期的系

15、统演化过程中,经过了严格的自然选择的优胜者,它们与当地的气候、土壤相适应,具有适应性广、抗病虫害能力高、抗逆性强等特点。二是树种要耐瘠薄、耐干旱、适应性强。由于公路工程挖、填方路段较多,土壤结构受到破坏,土壤肥力不高,同时路面宽阔,辐射强烈,小气候气温较高,因而要求绿化树种要具有良好的保持水土的作用,并要达到易生长、易成活、抗病虫、繁殖易、耐干旱、耐瘠薄、耐粗放管理等要求。三是要注重生物多样性原则。Highway slope selection of plant species to abide by the following principles: one is dominated by

16、native species. Native species is in the evolution of long-term system process, after rigorous natural selection of winners, they adapt to the local climate, soil, has the characteristics of wide adaptability, disease and insect resistance, strong resistance etc. The two tree species to barren, drou

17、ght tolerance, adaptability. Because there are a lot of highway excavation, embankment, the destruction of soil structure, soil fertility is not high, at the same time, wide roads, strong radiation, microclimate temperature is high, so the requirements of greening tree species to have good soil and

18、water, and to achieve the growth, survival, reproduction, disease and insect resistance, easy tolerance to drought, barren, resistance and extensive management requirements. Three is to pay attention to the principle of biodiversity. 综上所述,公路养护管理中边坡养护管理是一个系统工程,影响因素很多。实践证明,应优先考虑采用植物防护,当土质不宜植物生长及难以保证边坡

19、稳定时,要考虑经济性、施工及效果,采用圬工防护或相应的辅助设施。对于公路边坡的养护要逐步达到恢复自然生态和美化环境的终极目标,最大限度地保障公路行车的通畅性与安全性,为提高公路使用寿命,增强公路企业的竞技力奠定坚实的基础。To sum up, maintenance management of highway slope maintenance management is a systematic project, many factors influence. Practice has proved, priority should be given to the use of plant

20、protection, when growth and soil slope stability is difficult to ensure the plant, to consider the economy, construction and effect, the masonry protection or relevant auxiliary facilities. For highway slope maintenance to gradually achieve the ultimate goal of restoring the natural ecological and beautify the environment, to maximize the protection of patency and safety of highway traffic, in order to improve the service life of the road, the highway enterprise competitive power enhancement and lay a solid foundation.
