Pile hammering stopping standard judgment method suitable for coral reef geology
The invention discloses a driving pile hammer stopping standard judgment method suitable for coral reef geology. The driving pile hammer stopping standard judgment method comprises the steps that pile position distribution of a matrix structure is preset; calculating the elevation change trend of each soil layer between the two primarily selected pile positions; constructing a three-dimensional geological map according to the position of the pile and the elevation information of each soil layer; selecting a plurality of piles as acceptance unit groups from the three-dimensional geological map slices according to the pile positions of each row or each column in rows or columns; after pile sinking construction of the piles of each acceptance unit group is completed, the hammering energy consumption of each pile in the acceptance unit group is calculated, and a reference pile is selected; and carrying out bearing capacity verification on the reference pile to judge whether the requirement is met or not, if yes, all the piles in the acceptance unit meet the hammer stopping standard, and otherwise, repeating the steps 2-4. Whether the other piles meet the hammer stopping requirement or not is judged based on bearing capacity verification of the reference pile, the test acceptance cost can be greatly reduced, the pile foundation construction acceptance efficiency is improved, time is saved, and the construction efficiency of the whole driven pile is remarkably improved.
本发明公开一种适用于珊瑚礁地质的打入桩停锤标准判断方法，包括：预设好呈矩阵结构的桩位分布；计算出两个初选桩位之间各土层标高变化趋势；根据桩的位置和各土层标高信息，构筑三维地质图；按行或列为每一行或每一列的桩位从三维地质图切片选择若干桩作为验收单元组；每组验收单元组的桩沉桩施工完毕后，计算出该组验收单元内的各根桩的锤击能耗，并选出基准桩；对基准桩进行承载力验证是否满足要求，若是，则该验收单元内的所有桩均满足停锤标准，否则重复上述步骤2‑步骤4。本发明基于基准桩的承载力验证来判断其余桩是否满足停锤要求，能够大大降低试验验收成本，提高桩基施工验收效率，节约时间，显著提高整个打入桩的施工效率。
