In landscape design, we often encounter various landforms. We can't level them all, and then do landscape design on them. Therefore, it is very important to make rational use of the terrain drop. Respecting the elevation difference can reduce the earthwork volume, reduce the damage to the current situation and reflect the site memory. The use of ingenious handling techniques can create a landscape design with a sense of hierarchy, making the height difference the highlight of landscape design.
The commonly used height difference treatment methods include steps, terrace planting belts, retaining walls, etc. The use of plants, cultural walls, landscape sketches, benches and other artistic treatment methods can create a better architectural environment, develop more space on slopes, relieve the pressure of insufficient land resources, and create more levels of space for human beings and create a more pleasant living environment.
1、 Design points of elevation difference treatment
1. Adapting measures to local conditions is an important principle of landscape design. For terrain with elevation difference, it is necessary to combine the status quo as far as possible and reduce excavation or backfilling as much as possible.
2. The use of elevation difference to create landscape is not only conducive to reducing project costs according to local conditions, but also conducive to creating rich garden space changes.
3. The form selection and section form of elevation difference road shall be determined according to the functional requirements and specification requirements.
4. Attention shall be paid to timely drainage of rainwater to avoid problems such as ponding in depressions or running water on the road during heavy rain.
2、 Design method of elevation difference treatment
1. Use ramp
In order to meet the requirements of barrier free design, ramps can also be designed when the elevation difference is allowed. The most wonderful is the combination of steps and ramps, which can produce many rich and interesting landscapes.
2. Use retaining wall
The retaining wall is also commonly used to solve the elevation difference. It is a fast and effective elevation difference treatment method. It can be used in various forms, such as concrete, stone wall or other materials. It can be selected and applied according to different styles and functions. The reasonable and beautiful landscape wall can effectively become the highlight of the landscape and add color to the project. During the selection of retaining wall, its bearing capacity shall be analyzed first, and the appropriate retaining wall form and material shall be selected according to the landform, hydrology and elevation difference to ensure that the retaining wall can be used safely and stably in the future, without inclination, and ensure the best landscape effect.
3. Create undulating landscape terrain
Creating undulating landscape topography can not only solve the problem of elevation difference, but also become a unique landscape.
4. Use steps
It is a very practical method to use steps to solve the elevation difference. Steps can be regular or natural in shape. The natural stone steps blend with the lawn in some changes, which can not only meet people's needs for walking, but also give people a sense of ease and leisure. Large scale step application can well reflect the magnificent momentum and highlight the noble and gorgeous building body by using the elevation difference. However, full consideration should be given to ergonomics to avoid fatigue.
