摘要
将管波探测法、孔旁透射波法和钻芯法综合应用于既有桩基检测。检测结果表明:三种方法均适宜既有桩基的完整性检测,且各方法查明的缺陷位置吻合。钻芯法仅可判定钻芯孔范围桩基的完整性;管波探测法可探测整个桩基的完整性;孔旁地震透射波法可区分承台、桩身的深度范围,可定性判别桩基的完整性;钻芯法与管波探测法的组合应为同类工程的最佳检测方案。
The tube wave detecting method,the paraller seismic test and the core drilling method have been adopted in detecting existing pile foundation.The detecting results indicates that these methods are suitable for detecting the integrity of existing pile foundation,and the positions of defect found by these methods coincides are identical.The core drilling method can determine the integrity of surrounding pile foundation of drilling core hole,while the tube wave detecting method is able to identify the defects of the whole pile,and the paraller seismic test can discriminate the depth range of the pile-cap and the pile body and determine the integrity of pile foundation qualitatively.Therefore the combination of the core drilling method and the tube wave detecting method is the optimal detection scheme in similar cases.
