| 中文摘要:基岩中存在软弱夹层为岩石的差异性风化的主要特征。在不均匀性地基土上选用该类地层作为钻孔灌注桩持力层时，它的存在将对桩长、单桩承载力、桩体沉降等带来不同程度的影响。以黄石电厂为例，指出在选用差异性风化岩石作为桩基持力层时应注意的若干问题。 |

| Abstract:In the diversity weathered rock stratum, there exist the soft intercalary strata, which, as its main character, will affect the pile length, load capacity, subsiding of pile in some extents. The article suggests that some attentions should be paid when the soft intercalary strata are taken as the support strata of the piles. |
