大型堆积体边坡的空间工程效应研究

Study on the spatial engineering effect of large accumulation slope

以堆积体边坡的空间工程效应为切入点,运用地质工程分析、数值模拟和物理试验等多种手段,通过对A、B 两个大型堆积体边坡的实例对比研究,剖析了堆积体的形态、结构、环境、演化等空间要素;提出惯性聚集,剩余下滑力扩散等空间效应机制,提出了堆积体变形失稳的空间特征,堆积体变形失稳控制途径。依据理论研究成果,对B 堆积体边坡提出具体的支护工程优化设计方案,大大减小工程投资。

Through the contrast study of deposit body A and B, the paper studied on the spatial engineering effect of large accumulation slope. In the study, we had used the methods of engineering geology analysis, numerical simulation and physics simulation and so on. The paper had dissected the space element which included modality, structure, surrounding and evolvement and so on, put forward the space effect mechanism, inertia-assemble and surplus slide-down power diffuse, put forward the spatial character of accumulation stability and its control approach. According to theoretical studies, writer optimized the timbering design of accumulation slope B, enormously, economized project investment of B.
