针对某工程两根冲孔灌注桩竖向抗拔静载试验不满足设计要求,建议设计冲孔灌注桩单桩竖向抗拔承载力特征值应考虑泥浆护壁的影响,宜通过现场单桩上拔静载试验确定,进行后注浆可以改善桩周土体性能,提高单桩竖向抗拔承载力。 In view of the fact that the vertical pull-up and static load test of two perforated cast-in-situ bored piles does not meet the design requirements, it is suggested that the characteristic value of vertical pull-out bearing capacity of single perforated bored pile should be considered considering the influence of slurry retaining wall. Static load test to determine pull, after the grouting can improve the performance of the soil around the pile to improve the vertical pile capacity of anti-pull uplift.
