摘要
通过对高速公路隧道洞口浅埋段施工技术的详细分析,不仅研究了预注浆、预支护、锚网喷、洞口土方刷坡等提高和改善洞口围岩自我稳定能力的加固技术,还探索了具体的高速公路隧道洞口浅埋段开挖的具体施工技术。希望通过这两者施工技术的详细研究,为广大高速公路施工者提供一定的理论指导和帮助。
Based on highway tunnel shallow buried the construction technology is analyzed in detail. It not only studies the surrounding rock of pre grouting, reinforcement, anchor net spray, portal earthwork brush slope improved hole self stabilizing ability of reinforcement technology, also to explore the specific highway tunnel portal shallow buried section excavation construction technology of concrete. It is hoped that through the detailed study of the two construction technology, it can provide some theoretical guidance and help to the construction of the highway.
