摘要
分析加筋土挡土墙发生失稳的原因,阐述采用喷网锚注加固技术应满足的原则和条件,重点论述了加固工程的施工工艺和关键技术。实践证明,喷网锚注加固技术能提高填土的物理力学性能,保证了挡土墙的可靠性,是适合于失稳加筋土挡土墙加固的工程技术。
Reasons of the failure of reinforced earth retaining walls were analyzed, and the principles and conditions for reinforcing the walls by spying-anchoring-grouting are set forth. Especially, the construction technology and crisis problems are expounded. Practice shows that the physics and mechanics performances of filling are reproved, and failure reinforced earth retaining walls are reliability. The method is fit for strengthening failure renforced earth retaining walls.
