Researchon The Interaction Between Mudflow And K2 Myeone-Dong Of The Ying Wen Highwey

Due to the effect of rainfall, the section of National Highway 213 from Yingxiu to Wenchuan occurred multiply debris flows. The section which is located in the K2 mudflow was destroyed and blocked by mudflows, causing traffic disruption. Through the deposition region in port area, the proposed myeone-dong ensures the secure and ordered traffic.On the basis of original geological dates, scene investigation and review, the essay introduces engineering geological problems occurred in Yingxiu to Wenchuan section of National Highway 213,and presents debris formation motion features dynamic characters susceptibility danger and relationship with road. It focused analyzes the interaction of K2 mudflow and proposed myone-dong. The study presents that the effect to the established myone-dong from the mudflow affect its safety. On the other hand, building myone-dong affects the stability of accumulated region. It lift the water of accumulated area, changes the moment path of groundwater and firely accelerates the deposition. By FLAC3D numerical simulation software the essay takes simulation analyses on the stability of un-build myone-dong and the deposition influence for established myone-dong from accumulated region. The condusion which is made is consistent with theoretical analysis. On the basis, the essay gives reasonable on the design of it.
