摘要
过去硐室形状优化一般是在围岩为弹性的假定下进行的，若原岩地应力很大时，可能再好的硐室断面形状也不能避免围岩的破坏，此时按弹性假定找出的硐室形状能否是最优．用算例给出了回答：按此方法确定的硐形，就硐室围岩的破坏程度而言，与其他硐形相比，仍然是最优的．
In the past,section configuration of underground chamber was optimized normally assuming that surrounding rock is elastic.If in situ strata stress is huge,then,even the best section configuration can not avoid damaging from surrounding rock.At this time,is the configuration selected before still the best one?The calculation gives the answer:the chamber configuration determined by the above method is still the optimized one comparing with other configurations on the damage degree of chamber surrounding rock.
