拟建的两江隧道工程是目前国内外技术最为复杂的隧道工程,根据隧址的工程地质及水文地质条件,两江隧道工程的越江方案在本阶段(可研阶段)拟定了盾构、沉管、钻爆等3种隧道方案。本文首先通过3种工法的简单分析和定性比较,然后从项目实施中的风险程度出发,采用定量的风险模糊分析方法,得出了各种工法的风险度,最后建议采用盾构施工法。
The proposed two-river tunnel project is currently the most technologically complex tunnel project at home and abroad. According to the engineering geology and hydrogeological conditions of the tunnel site, the cross-river project of the two-river tunnel project at this stage (feasibility study stage) Blasting and other 3 kinds of tunnel program. Based on the simple analysis and qualitative comparison of the three kinds of work methods, the paper starts from the degree of risk in the project implementation and adopts the quantitative risk fuzzy analysis method to get the risk of various work methods. Finally, the shield construction method is suggested.
