| Abstract: | The experience in Beijing underground railway construction was introduced, where the design by shallow cover underground excavation method and construction with NAM principles were applied. A detailed investigation experience both at home and abroad in combination with engineering practice was carried out. The distinction etween deep, shallow and super shallow covers for friable strata was established. The influence of gap between complex linings on safety factors of the structure was pointed out and the measures for lowering cost for shallow cover under-ground excavation were suggested. Its experience is useful to underground construction with similar conditions. |
