CRD工法在黄土隧道塌方处理中的应用

The application of CRD construction method in loess tunnel collapse treatment

结合工程实例,针对工程坍塌情况,提出采用CRD工法进行处理,并制定了具体的处理方案,着重对回填塌腔体、洞身二次开挖及支护衬砌方法进行了介绍,实践证明采用CRD方法对黄土隧道塌方处理是可行的。

Combining with engineering example, according to the project collapse situation, put forward using CRD construction method for processing, and developed specific processing scheme, emphatically introduced the backfill collapse cavity, barrel secondary excavation and lining method, the practice proved that using CRD method was feasible to treatment of loess tunnel collapse.
