摘要
分析了大呼高速公路路基出现沉降裂缝的原因,介绍了采用高压旋喷注浆工艺进行路基治理的措施。实践表明,该技术可在不影响高速正常运行的条件下安全施工,达到预期目的。
The paper analyzes the causes of settlement cracks in Datong - Hohhot expressway and introduces the measures for subgrade treatment with high pressure jet grouting technology. The practice shows that with this technology, the treatment construction can safely carried out with normal traffic remaining.
