城市复杂环境矩形过街通道浅埋暗挖施工技术研究

On Shallow Buried Excavation Construction Technique for Rectangular Section of Underpass Under Complex Urban Environment

在运营繁忙的公路和正常使用的地下管线下修建下穿暗挖通道等地下工程时,既要考虑承受汽车动载作用,还需考虑管线下沉造成的影响。以胶州市民广场人防工程澳门路、香港路过街通道为例,针对该类型通道具有矩形大断面、穿越管线多、薄覆盖层等特点的情况,研究并采用城市复杂环境矩形过街通道浅埋暗挖施工技术。

When carrying out underground construction such as tunnel digging under busy operating roads and normally used underground pipelines, it is necessary to consider the influence of vehicle dynamic load as well as the influence of pipe- line sinking. This paper takes the civil air defense engineering of Macao Road and Hong Kong Road in Jiaozhou Civil Square as an example, and carries out a study and implementation of underpass amnel digging by using shallow buried excavation construction technique under the complex urban environment. The tunnel features rectangular section, pipeline crossing and thin covering layer.
