[0002] The common geological environment in southwest my country is characterized by high and steep terrain, complex geological environment and frequent landslides. As a result, the site selection and disaster prevention of dense housing complexes face many complex geological and geotechnical engineering problems, especially the construction of dense buildings on relatively gentle landslide deposits. Due to their poor anti-disturbance and easy slippery properties, they face more complex construction site safety control problems. However, these landslide deposits often have relatively good terrain, water sources, land and transportation conditions. Many township or enterprise buildings are built on them, which has triggered many catastrophic geological disasters.

[0003] Therefore, during construction, the slope must be supported, and the most commonly used traditional landslide reinforcement technologies include anchor rod and cable method, grouting method, retaining wall reinforcement method, and anti-slide pile reinforcement method.
