宜兴公路Ⅱ号边坡稳定性分析
|
摘要
目前,边坡失稳的防治仍然是一项很艰巨的任务,对边坡的稳定性分析及处治技术进行深入研究具有重要的意义。本文详细介绍了宜兴公路边坡的工程概况,场地工程地质条件、岩土体的物理力学性质及其稳定性的分析和支护方案的设计。分析及计算证明,该边坡不符和稳定要求,需要进行支护,运用理正软件设计支护方案,本边坡支护设计方案在满足边坡稳定性的情况下兼顾降低工程造价以及支护工程施工的可行和方便。
At present, the prevention and control of slope instability is still a very difficult mission. It is of great significance to conduct in-depth study on slope stability analysis and treatment technology. This paper introduces the engineering situation of yixing road slope, the engineering geological conditions, the physical and mechanical properties of rock and soil mass, the stability analysis and the design of support scheme. Analysis and calculation show that the discrepancy and slope stability requirements, the need for support, using reason is the software design support scheme, the slope supporting design scheme in the slope stability under the condition of both lower the project cost and support engineering construction is feasible and convenient.
