公路路基融陷的注浆处理技术

Technique of treating highway subgrade thaw with slip casting

论述了采用注浆技术处理公路路基融陷的机理、技术要点 ,并通过工程实例介绍了施工工艺及处理效果。工程结束后 ,经观测表明沉降情况由减弱直至完全消失 ,表明注浆达到了加速冻土解冻和加固软土路基的目的 。

The paper discusses principle and technical major points of treating highway subgrade thaw with slip casting technique, introduces construction technology and treating effect by engineering examples. After the project ends, observation indicates that subsidence is from weakened to disappear entirely. It indicates slip casting achieves the goal of accelerating frozen soil thaw and strengthening soft soil subgrade. It's bearing capacity and stability much improve.
