以兰州重离子肿瘤治疗中心灌注桩后压浆工程为例，根据其所在区域的地质条件下，对比分析了后注浆桩基与普通桩基的承载力极限值，结合基桩完整性测试试验，对试验桩的桩身完整性进行了分析，对比了同等条件下，缺陷与非缺陷桩基沉降在数值上的差异，并分析了缺陷位置对桩身沉降的影响。试验证明：后注浆桩基的优势在该地区表现明显，承载力明显高于普通桩基，缺陷桩基与非缺陷桩基在同等加荷条件下，两者沉降差异不明显。

Taking Lanzhou heavy ion cancer therapy center pile after grouting foundation engineering as an example,the geological conditions of the region are analyzed,the ultimate bearing capacity of grouting pile after pile and common values,combined with low strain integrity testing, to test the integrity of piles are analyzed,the same conditions the difference in the value of the settlement,defect and non defect pile foundation,and analyzed the influence on the pile settlement of defect location.Experiments prove:the post grouting pile advantages in the area was significantly higher than normal,the bearing capacity of pile foundation,pile foundation defect and non defect pile foundation under the same loading conditions, the settlement difference.
