CRD工法与双侧壁导洞工法的施工转换

Conversion Technology Between The Method CRD and Double-side Drift

由于地质条件较差,地表降水量增加,厦门海底隧道A2标陆域全强风化地段,洞内支护变形严重。根据现场实际条件,详细介绍CRD工法转换为双侧壁导洞工法。

Because of poor geological conditions, increased precipitation surtace, Xiamen Harbour Crossing A2 Land-wide standard-weathered lots, inside support deformation serious. According to the actual conditions at the scene, the details of the CRD converted to double-wall-guided method.
