摘要
文中以厦门市新324国道某提升改造工程为例,采用孔内摄像法对灌注桩钻芯结果进行验证和比对,取得了较好的效果。在钻芯法试验难以准确鉴别桩底持力层性状、判别桩身完整性及桩底沉渣厚度测量时,进行孔内摄像法验证和比对十分必要。
In this paper,taking a lifting and reconstruction project of New 324 National Road in Xiamen as an example,the borehole camera method is used to verify and compare the core drilling results of cast-in-place piles,and good results have been achieved.When it is difficult to accurately identify the behavior of bearing layer at the bottom of pile,judge the integrity of pile body and measure the thickness of sediment at the bottom of pile by core drilling method,it is necessary to verify and compare it by in-hole camera method.
