摘要
嵌岩桩承载力主要由桩端承受,桩端嵌岩质量是决定桩基施工质量的关键。介绍超前钻勘察要求及桩基入岩判断、桩底沉渣厚度控制等关键点的控制及相应的施工检验要求,叙述钻芯法检测在嵌岩质量验收中的重要作用。
The main loads of insert rock pile is resisted by the pile tip. The quality of insertingin rock is the key point that decides the quality of pile construction. In this paper, a method isintroduced that can control the key points in construction , including the judgment of the pile intothe rock , the thickness control of the bottom sediment. The inspection requirement of each key pointin construction is proposed in this paper. As a result, the core drilling method plays an important rolein the quality acceptance.
