分析人工挖孔桩水平裂缝产生的原因,采用低应变及钻芯验证检测方法确认水平裂缝的存在,采用高压注浆对水平裂缝进行封闭。提出人工挖孔桩施工应注意的细节以减少水平裂缝的产生。
The reason of the horizontal cracks in the manual digging piles was analyzed. The existence of horizontal cracks was confirmed by low strain and core verification testing method, and the horizontal cracks were closed by high pressure grouting. The construction of artificial digging pile should pay attention to the details to reduce the horizontal cracks.
