How to determine surroundingrockpressure is always the key of tunnel structure design.
隧道结构设计的关键在于确定隧道围岩压力。

The results show that, for relatively shallow embedded tunnel, a big error would occur if the surroundingrockpressure of the vault is regarded as uniformly distributed.
结果表明：对于埋深较浅的隧道，如果拱顶围岩压力按均布进行计算，结果会产生较大误差。

The relationship of roadway surroundingrockpressure and supporting performance is interacting and counteracting. Only coordination between them can make possible a better support.
