莞番高速老虎岩挖方路基改隧道方案研究

Study on the Scheme of Transforming excavated SubGrade into Tunnel in Laohuyan of Guanpan Expressway

以广东省高速公路加密线东莞至番禺高速公路(以下简称“莞番高速”)为工程实例,基于实施条件、工期、行车仿真模拟等因素,对莞番高速老虎岩挖方路基因高压线迁改难而调整为隧道方案进行研究,经论证隧道方案具有实施的可行性。上述研究结果为今后类似项目实施提供了参考。

Taking Dongguan to Panyu Expressway(hereinafter referred to as"Guanpan expressway")as an engineering example,based on the implementation conditions,construction period,driving simulation and other factors,this paper studies the tunnel scheme for the high-voltage line of laohuyan excavated subgrade in Guanpan expressway,which is difficult to be relocated.It is proved that the tunnel scheme is feasible.The above research results provide a reference for the implementation of similar projects in the future.
