Research on Slope Reinforcement Method of Prestressed Anchor Cable Technology for Railway Subgrade Engineering in Mountain Areas
Due to the poor ability of traditional slope reinforcement methods for railway roadbed engineering in mountainous areas in selecting reinforcement materials and the lack of precise analysis of mountainous environments,frequent settlement and large settlement values occur in the reinforced subgrade.Therefore,a slope reinforcement method using prestressed anchor cable technology for railway subgrade engineering in mountainous areas is proposed.Firstly,based on the safety factor of anchor cables in mountainous areas,the anchor cable anchoring section is divided into two parts:tension type and pressure type,and the prestressed anchor cable anchoring design is completed.Then,finite element analysis and displacement difference function calculation are used to predict the settlement data of railway subgrade engineering in mountainous areas.Finally,according to the Technical Code for Building Slope Engineering(GB 50330-2013),anchor installation parameters and construction methods are set,and anchor cable technology is applied to slope reinforcement methods.Based on the actual soil samples in the experimental area,construct a simulated experimental groove.The experimental results show that this method can effectively control the settlement and displacement of railway subgrade,further achieving the reinforcement of the subgrade.
