超大断面超小净距交叉隧道施工安全风险分析

Safety risk analysis on construction of superlarge cross section and super small clear distance intersection tunnel

以大横琴山隧道和珠海机场城际轨道交通铁路隧道(以下简称珠机城轨)重叠交叉段为研究对象,搜集调研类似工程,通过风险评估,定性分析两拟建隧道工程的相互影响,综合判定评估对象的影响程度,同时提出建议和加强措施,保证隧道工程的安全施工。

This paper takes the overlapping section of Dahengqin Mountain Tunnel and Zhuhai Airport Intercity Rail Transit Railway Tunnel(hereinafter referred to as Zhuhai-Jiangsu Urban Rail)as the research object.Similar projects were collected and investigated.Then,through risk assessment,qualitative analysis of the mutual influence of the two proposed tunnel projects,comprehensively determine the influence degree of the evaluation object.At the same time,suggestions and strengthening measures are put forward to ensure the safety of tunnel construction.
