植被混凝土在高陡岩石边坡中的试验与应用

Experiment and Application of Vegetation Concrete in High and Steep Rocky Slopes

摘要:

南山区前海路（棉山路—妈湾大道段）工程位于现状小南山脚下，需破除小南山坡脚石方后形成路基，边坡岩石以微风化花岗岩为主，为减少开挖面，岩石坡比为1∶0.2，最高边坡约45 m，属于高陡岩石边坡。为了践行“绿水青山就是金山银山”的发展理念，还小南山一个完整的山林，引用了植被混凝土修复技术。有针对性的进行植被混凝土的配比试验和植物种子的筛选试验，最后选择了一组最优的植被混凝土配比和长势良好的物种配比。目前经过两年半的自然生长，基本实现了高陡岩石坡面植被生境的构建，生态修复效果良好，可为类似工程提供参考和借鉴。

Abstract:

The Nanshan District Qianhai Road (Mianshan Road - Mawan Avenue) Project is located at the foot of the current Xiaonan Mountain. It is necessary to remove the stones at the foot of the Xiaonan Mountain slope to form a roadbed. The slope rock is mainly slightly weathered granite. To reduce the excavation face, the rock - slope ratio is 1∶0.2, and the highest slope is about 45 m, belonging to a high and steep rocky slope. In order to implement the development concept that “Green mountains and clear waters are as valuable as gold and silver” and return Xiaonan Mountain a complete mountain forest, the vegetation concrete restoration technology is adopted. For this project, the ratio test of vegetation concrete and the screening test of plant seeds are carried out. Finally, a set of optimal proportions of vegetated concrete and species with good growth are selected. At present, after two and a half years of natural growth, the construction of vegetation habitats on high and steep rocky slopes has been basically achieved, and the ecological restoration effect is good, which can provide the references for similar projects.
