摘要
本文介绍了综合注浆预加固技术在城市有荷载浅埋暗挖隧道施工中的应用 ,根据现场土质试验对文献 [3]建设的经验公式进行了适用范围的扩展。通过应力检测结果验证了该技术在实际施工应用中具有可操作性强 ,预加固效果显著 ,能有效控制洞顶的沉降量 。
In this paper, the complex grouting consolidation technique for tunneling the urban shallow loaded tunnel is introduced. Based on data from in situ soil test, the empirical formula presented in literature (2) is expanded. The stress test results have verified this technique, which is operable with significant effect and the settlement of tunnel roof can be well controlled to ensure the safety of construction and on ground buildings.
