夯实水泥土桩桩身完整性检测分析

摘要

Using the low strain reflected wave method, this paper tested and analyzed the pile integrity of a engineering using sand lime soil pile, the results showed that:its wave characteristics, wave velocity variation, amplitude attenuation characteristics uniformity to pile integrity, the pile had good material, the pile with good compactness, high wave speed, the ratio was higher of reflection wave amplitude and incident wave ampli-tude, and the opposite small.%采用低应变反射波法，对某工程所采用掺砂灰土桩的桩身完整性进行了检测分析，结果表明：其波形特征、波速变化、波幅衰减特性与桩身完整性相关，桩身材质均匀，密实度好的桩，波速高，反射波幅与入射波幅比高，反之亦小。
