摘　　要：预应力钢锚管支护技术是岩土工程中的一种新型锚固技术。本文结合工程实例,研究了深路堑高边坡预应力钢锚管支护技术的设计方法、加固机理及施工工艺,并对其受力特点进行了分析,揭示了预应力钢锚管技术在高速公路边坡加固工程中的理论价值和应用意义。实践表明,此技术是解决滑坡问题的经济适用的方法。The retaining technique with pre-stressed steel anchor pipes is a new-type anchoring technique in geotechnical engineering. Combined with the project examples, the reinforcing mechanism, the design and the construction of the said technique are studied, and the stress distribution characteristics are analyzed, which explore the theoretic values and application significance of pre-stressed steel anchor pipes on the reinforcing engineering of slope in expressway. Through the construction practice, it indicates that the technique is an economic and effective method in solving the problem of landslide.
