Landslide emergency treatment refers to the engineering technology which makes the landslide deformation under control by taking effective mechanical control measure before sliding. Landslides extensively exist in southwestern China, which represent a direct threat not only to the safety of people and facilities in the landslide front areas, but also to that of the major facilities or houses in the slope or the trailing edge areas. While the landslide now has been in the limit equilibrium state, which is very sensitive to external factors; mechanical control measures, such as earth-retaining walls and anti-slide piles, with the disadvantages of mass excavation volume, low construction speed and great interference to the slope, is not conducive to seize the preemptive opportunities of landslide emergency management, to protect the stable and keep the landslide from sliding and temporality protect the major facilities or houses. Hence micro steel pipe pile may after all be accepted as a productive mechanical control measure to, which is simple and easy to carry out and economic and reliable. Taking the example of Wenjialiang landslide emergency repair, this paper studies the important role of micro steel pipe pile in the landslide emergency treatment.
