摘要
介绍劲性微型桩在地下洞室塌陷事故中的应用，劲性微型桩因其桩内型钢刚度大、承载力高，能克服因地基局部软弱而产生的缩颈及断桩对其承载力的影响，在地基加固及基础托换中应用前景较好。
I shaped steel reinforced micro pile is described in the accident of shelter collapse under building foundation.With the I steel in the core,higher rigidity and strength can be gained which decrease the effect of pile radial shrinkage and will be applicable to soft soil reinforcement and foundation underpinning.
