长沙市旺东物流园建设对既有铁路隧道的影响评估

长沙市新建旺东物流园周边临近既有铁路,须在石门至长沙铁路北西联络线隧道上填土堆载,并临近隧道进行桥梁桩基施工,对既有铁路隧道造成较大影响。本文通过对铁路隧道的模拟分析进行强度、裂缝、位移等多项指标检算验证,同时提出一系列工程应对措施,以确保铁路隧道安全和列车运行安全。

Evaluation for Influence of Changsha Wangdong Logistics Park Construction on Existing Railway Tunnel

Since the new-build Wangdong logistics park is near the existing railway,filling and loading must be operated on the connective tunnel between the north and the south part of Shimen-Changsha railway,and bridge pile foundations need to be constructed near the tunnel.This will cause a great impact on the existent railway tunnel.This paper will demonstrate various indices regarding strength,cracking and displacement of the railway tunnel,verify them and come up with a series of effective countermeasures in order to ensure the safety and security of railway tunnel and train operation.
