【摘要】：工程桩地质勘察入岩判定错误,导致桩底持力层夹杂0.9m厚强风化岩层及残积砂质岩层,为保证桩身承载力,确保桩身不下沉,采取了水洗置换注浆法对工程桩进行了补救,经现场大应变检测,桩身承载力满足要求。
[Abstract]:In order to ensure the bearing capacity of the pile body and ensure the pile body does not sink, the engineering pile is remedied by the method of water washing replacement grouting in order to ensure the bearing capacity of the pile body and ensure the pile body does not sink, resulting in the pile bottom bearing layer being mixed with 0.9m thick strong weathering rock and residual sand rock stratum. It is found that the bearing capacity of pile body can meet the requirement by field testing with large strain.
