Evaluation of drainage tunnel effectiveness in landslide control

摘要: Infiltration of rainfall into hillslopes is often an important factor in triggering landslides. Using underground water drainage works together with anti-slide piles has been effective method landslide control, yet their effectiveness inadequately discussed the literature. This paper studies influence on change level beneath a slope by real-time and synchronic monitoring rainfall, boreholes, flow rate tunnel. The tunnel preventing rise discussed. researchers also study deformation behavior lateral displacement analyzing thrust that bear numerical inversion techniques. results indicate there apparent relationship between lag rising caused immediately previous rainfall. When accumulation before occurrence heavy rain, this particular will cause rapid slope. data analysis shows increases first, then rises after In other words, at faster than level. Hence, can effectively lower induced Besides, based subsequent analysis, working state justified. It thus indirectly validates benefits using control.
