The invention relates to a novel debris flow pile group type blocking structure and method. The novel debris flow pile group type blocking structure comprises at least three rows of pile bodies. In the flow direction of debris flow, flow dividing type piles are placed firstly, then flow guiding I type piles are placed, and finally flow guiding II type piles are placed. When the debris flow flows through the first row of piles, the debris flow is divided, and the debris flow flows to different functional areas. The steering of the debris flow is guided between the rows of piles through curved surfaces, the debris flow intersects with incoming flow debris flow, and a mixed energy dissipation area is formed so as to conduct energy dissipation on the debris flow. After the debris flow is divided, guided, steered and oppositely impacted step by step, the flow speed and kinetic energy of the debris flow are reduced step by step, finally, the debris flow migration distance and impact force ona protection object are reduced, the disaster degree and range are weakened, and the safety of the protection object is improved. Compared with the prior art, the novel debris flow pile group type blocking structure and method have the beneficial effects that structure stress is more reasonable, the structure is more stable, and the economic cost is low.
本发明涉及一种新型泥石流桩群型拦挡结构及方法，包括至少三排桩体；沿泥石流流向，首先放置分流型桩、其次放置导流Ⅰ型桩、最后放置导流Ⅱ型桩；泥石流流经第一排桩时对泥石流进行分流，使泥石流流向不同的功能区；各排桩之间通过曲面引导泥石流的转向，与来流泥石流交汇，形成混杂消能区以对泥石流进行能量耗散；泥石流被逐级分流、引导、转向、对冲后其流速和动能逐级降低，最终降低泥石流运移距离和对防护对象的冲击力，减弱受灾程度和范围，提高防护对象的安全性。与现有技术相比，本发明具有结构受力更为合理、结构更为稳定、经济成本低等优势。
