竖直方向小净距隧道的方案优化研究
|
摘要
本文基于工程实践,运用工程类比分析、数值模拟、实施现场试验段、现场监控测试等方法,研究上下交叉的小净距隧道的开挖和支护方案,保证了在顶板厚度仅2.9m的情况下,客运铁路专线双线隧道顺利下穿高速公路隧道。
Based on the railroad Guantouling tunnel DK280+950～281+100 through under the highway tun- nel,the excavation method and support scheme are dicussed by the means of engineering analogical method,numeri- cal analysis,in-situ testing section,monitoring measurement.It is assured that the double line tunnel of passenger dedicated railway lines crosses under the highway tunnel successfully under the condition that the thickness of the tun- nel roof is only 2.9m.
