摘要
辅助以孔内摄像技术,钻芯法可以更精准评判桩身的缺陷类型、位置与严重程度,以及桩底沉渣厚度和持力层岩土性状,尤其是水平裂缝缺陷,进而显著提高高应变法桩土模型参数的准确性。综合测试方法有效地保证了灌注桩高应变法承载力检测分析结果的科学性和准确性,解决了大直径灌注桩高应变测试分析的技术难点。
Assisted by hole camera technology,core drilling method could be more accurate evaluation of the pile defect type,location and severity,and bottom sediment thickness and bearing s tratum of soil behavior,particularly horizontal fracture defect,thereby significantly improve the high strain method the accuracy of the pile-soil model parameters. Comprehensive detecting methods effectively ensure the scientific and accuracy of high strain pile bearing capacity of detection results of the analysis method,solve the technical difficulties of the high strain test analysis of large diameter pile.
