摘要
本文对铜汤高速公路路堑高边坡的失稳机理进行研究分析,提出一些综合治理措施和方法,同时通过具体工程实例验证其应用效果。从经济、环保、安全的角度考虑,边坡治理由于没有固定的模式可供参考,故只能根据现场条件选择合理的治理方案。在建设阶段,要遵循信息化施工、补充勘察、动态设计的原则,进行边坡的"动态综合治理";在公路营运阶段,由于边坡的蠕变、应力释放等,将继续若干年并受其它不稳定因素影响,因而必须对重点边坡进行长期监测,以确保边坡安全。
In this paper, the instability mechanism of high cutting slope in the construction of Tangling- Tangkou highway has been studied, some measurement and methods for sythetical treatment were provided, and the effectiveness of treatment has been proved by some practical engineering programs. From the consideration of economy, environmental protection and safety, no fixed model of slope treatment exist there for references; there- fore the reasonable treatment design only is prepared according to conditions in site. During the period of construction, it should be complied with the principles such as information construction, supplementary investigation and dynamic design to carry out the synthetical dynamic treatment of slope, and the focuses must be put on the monitoring to safety in the period of operation.
