Anti-upheaval method for subway tunnel under construction
The invention relates to the technical field of tunnel construction, in particular to an anti-upheaval method for a subway tunnel under construction. The anti-floating measure of the overlying structure and the anti-upheaval measure of deep hole grouting in the tunnel are utilized, so that upheaval of the subway tunnel under construction during excavation of the upper foundation pit is effectively relieved, and a permanent anti-floating system of a newly-built structure is formed. According to the anti-upheaval method for the subway tunnel under construction provided by the invention, non-synchronous design of underground engineering and peripheral development is completed, and in a synchronous construction project, the temporary anti-upheaval requirement of excavation of a structural foundation pit on the tunnel under construction is ensured by improving a permanent anti-floating system of a peripheral development structure; and the permanent anti-floating requirement of the structure is met. The obtained result has important theoretical and practical significance for development and utilization engineering along the subway, and the economic benefit is remarkable.
本发明涉及隧道施工技术领域，特别是涉及一种在建地铁隧道抗隆起方法。本发明利用上覆结构的抗浮措施以及隧道内深孔注浆的抗隆起措施，从而有效地减轻了上方基坑开挖期间在建地铁隧道的隆起，并且形成了新建结构的永久抗浮体系。通过本发明提供的在建地铁隧道抗隆起方法，完成了地下工程及周边开发非同期设计、而需同期施工工程中，通过对周边开发结构永久抗浮体系的改进，既保证了结构基坑开挖对其下在建隧道的临时抗隆起要求，又满足了该结构的永久抗浮要求。所得成果将对地铁沿线开发利用工程具有重要的理论和实践意义，且经济效益显著。
