摘　　要：为实现盾构机安全快速通过浅埋暗挖隧道,研发了一种盾体与台车分离分别前行的方法。该技术使用混凝土导台作为盾体支撑,导台上铺设钢轨做为盾体行走轨道,通过两台50 t在轨重物推移机做为盾体推进动力,推动盾体在轨道上前行,从而实现盾构安全快速通过浅埋暗挖隧道。文章通过对盾构过暗挖隧道技术原理进行分析,指出了技术控制要点,并对现场施工效果进行了研究。In order to achieve safe and rapid passage of shield tunneling machines through shallow buried tunnels,a method has been developed to separate the shield body and the trolley and move them separately.This technology uses a concrete guide platform as the support for the shield body,with steel rails laid on the guide platform as the walking track for the shield body.Two 50 ton on orbit weight pushing machines are used as the propulsion power for the shield body,pushing it forward on the track to achieve safe and fast passage of the shield through shallow buried tunnels.The article analyzes the principle of shield tunneling through underground tunnels,points out the key points of technical control,and studies the on-site construction effect.
