Remedy Solutions for a Deep-Seated Landslide on Road No. 155, Section Km 12 + 667.85–Km 12 + 711.57, Sapa Town, Lao Cai Province, Vietnam
Landslide hazards are geological disasters caused by heavy rainfall and debris flow, mainly occurring in mountainous regions. This paper presents remedy solutions for a deep-seated landslide on Road No. 155, section Km 12 + 667.85–Km 12 + 711.57, near a new Mong Sen bridge in Sapa town, Lao Cai province. In October 2020, two deep-seated landslides occurred in this area with some serious cracks. The landslide area was divided into two zones: zones 1 and 2, and up to date, these two zones have still been under reinforcement. While these two zones were reinforced with the retaining structure, soil nails, and grounded anchor system, a landslide (named Zone 3) happened in the area between Zones 1 and 2, where soil erosion and water erosion appeared serious because of heavy rainfall and cutting slopes. In this study, geological investigations, laboratory tests, topographical features, hydrological features, and stability analysis (Geo-Slope/W software) were studied and analyzed to understand the failure mechanism. Then, mitigation solutions such as the retaining wall with the ground anchors, drainage pipe, and soil nails were proposed for the reinforcement. The analysis results showed that the sliding surface of the entire landslide body and the behavior of the new cut slope, with and without reinforcement structures, were based on the numerical analysis by Geo-Slope/W software.
