摘要
探讨大直径钻成孔灌注桩在桩基施工中,当钻机的钻头在坚硬的岩层中钻进时,其对周围建筑物振动影响的监测方法及评价标准,同时结合工程实例讨论了土层质点振动速度的检测技术,以及振害防治措施等有关问题。
In the paper measurement methods and appraisal standards of the vibration effect on surrounding buildings are studied, which is induced by large diameter bored cast-in-place pile in its piling process.Testing method of the vibration velocity in soil layers with its engineering application,and the measures of preventing and controlling vibration damage to buildings are also discussed.
