徐州轨道交通2号线下穿陇海铁路道岔方案研究

Study on the Turnout Scheme of Xuzhou Rail Transit Line 2 underpassing Longhai Railway

徐州轨道交通2号线下穿陇海铁路徐州西站咽喉区道岔是整个工程建设中极其危险的风险源,本文通过对道岔改移方案比选、盾构通过陇海铁路沉降影响计算、施工保护措施等几个方面分别展开论述,期望本工程能为类似工程提供参考和帮助。

Xuzhou Rail Transit Line2underpassing Longhai Railway Xuzhou West Station throat turnout is the most dangerous risksource in the construction of the whole project.Through the comparison of the turnout scheme,the influence of the shield on the settlementof Longhai Railway is calculated.Construction protection measures and other aspects are discussed.It is expected that the project canprovide reference for similar projects.
