粒状碎屑溜砂坡树根桩固砂防护技术

Consolidation techniques by micro-root pile

粒状碎屑溜砂坡综合加固防护技术包含控制封闭砂源区、稳定砂坡体和保护砂坡脚3部分措施。从稳定砂坡体和保护砂坡脚的一般措施入手,通过野外调查和室内模型试验,探讨花管微型树根桩固砂机制、设计要点及固砂技术。

There are generally three ways to stabilize sand-sliding slopes composed by granular clast： controlling and blocking the sand source, stabilizing the slope and protecting the slope toe. In this paper, the techniques of consolidation by perforated pipe micro-root pile are introduced. The sand-shding slope consohdation mechanism and design theory of perforated pipe micro-root pile was studied based on field investigation and model tests.
