同高速公路快速发展相伴的是边坡数量的剧增,由于工期短,设计时对边坡的地质情况了解不足以及施工期间对边坡防护加固重视不够等因素,从而诱发山体变形,引起开挖边坡坡面发生局部的坍塌、连续的裂缝和错台,迫使公路改线并造成一定范围的生态破坏。文章提出了一种新型柔性防护体系——塑料土工挡墙防护体系。塑料土工挡墙与常见防护体系相比,具有结构轻、施工简便、造价低廉的优点,特别是其表面的绿色,在公路建设中,能够满足美化沿线景观的要求,应用前景广阔。
Along with the rapid development of the expressway, there is a sharp increase in the number of slopes. Due to the short construction period, insufficient understanding of the geological conditions of the slope at design time and insufficient emphasis on slope protection and reinforcement during construction, the mountain deformation is induced and excavation is caused Local slope collapse, continuous cracks and dislocation, forcing the highway to reroute and cause a range of ecological damage. The article presents a new type of flexible protection system - plastic earth retaining wall protection system. Compared with common protection system, plastic geotechnical retaining wall has the advantages of light structure, simple construction and low cost, especially its green surface. In highway construction, it can meet the requirements of landscaping along the landscape and has wide application prospect.
