Abstract
This paper focuses on the landslide remediation engineering design for the K242 + 500 - K242 + 600 section of a certain expressway, adopting an anti-slide pile support scheme. Firstly, common support methods are introduced, including anti-slide piles, prestressed anchor cables, lattice anchor structures, and prestressed anchor cable lattice beams, providing a background reference for subsequent design. Then, a detailed description of the slope conditions is presented, covering the overall engineering situation, natural geographical conditions, and engineering geological conditions, which offer fundamental data for the design. In the design concept section, the main design scheme ideas, design basis data, design principles, and design parameters are clarified. During the landslide mass stability calculation phase, following the basic principles, corresponding calculation methods are employed to obtain the landslide thrust, providing key parameters for the anti-slide pile design. In the part of anti-slide pile design methods, a comprehensive introduction to the overview, design requirements and contents, load determination, calculation methods, and specific design process of anti-slide piles is provided, with a detailed design carried out for the anti-slide piles at the K242 + 588.41 cross-section. The construction organization design for the engineering anti-slide piles outlines plans from aspects such as construction preparation, sequence, quality requirements, quality assurance measures, and rainy season construction safeguard measures. The monitoring scheme design for the engineering anti-slide piles clarifies the monitoring objectives and makes arrangements for safety monitoring during the construction period and long-term monitoring of the remediation effect during the operation period, respectively. In addition, the drainage and greening engineering designs for the landslide are conducted. Following the drainage design principles, a drainage system is designed, and a greening project is planned. Through the above comprehensive design, the aim is to effectively remediate the landslide problem in this expressway section and ensure the safe operation of the road.
