【摘 要】In the public underground works, because of underground
obstacles and restrictions of surrounding environment, shallow tunneling
method is usually used. Its prominent advantage is suitable for urban soft
formations, does not affect the city traffic, no pollution, no noise, and is
suitable for a variety of sizes and section forms of the tunnel cavern.
Combined with the construction practice of Zhengzhou Metro Line-1 02-contract section Zhengzhou University-Eastern Zhongyuan road station
underground-cut section tunnel, this paper studied the construction
technique of shallow tunneling method for tunnel earth excavation,
introduced the construction technique and method of up and down stairs
ring reservation core soil method and CRD method.%在公用地下工程中,因地下障碍物和周围环境限制通常采用浅埋暗挖法施工。它的突出优势在于适用于城市松软地层,不影响城市交通,无污染、无噪声,且适合于各种尺寸与断面形式的隧道洞室。本文结合郑州地铁1号线02合同段郑耀中暗挖区间隧道施工实践,对浅埋暗挖法隧道土方开挖施工技术进行研究,主要介绍了上下台阶环形开挖预留核心土法、CRD法的施工工艺以及施工方法。
