This paper examines the the holistic heterotopia and fluctuation phenomena of the sonic wave curves. The curves are obtained through sonic contrastive tests in single bore. Some contrasts are made among the curves integrated with the actually sonic test data. On the basis of contrasts, concrete manifestation and characteristic feature of the abnormity are presented. Then the mainly reason for this abnormity is analyzed. The result demonstrates that the sonic test abnormity is mainly caused by substandard test operation. In particular, the holistic heterotopia associated with the sonic wave curves was caused by the erroneous sampling. It belongs to linear systematic error, and can be dealt with increasing the length of contrast rockmass units, which is in order to increase the overlap ra-tion of sampling mass. But the holistic uneven fluctuation in the sonic wave curves is mainly related to the purity of the water that was used as the coupling reagent in sonic test. It belongs to nonlinear systematic error. So this abnormity is difficult to be remedied. This study offers some references to avoid or remove the abnormity occurring in the contrast sonic test.%声波测井技术在岩土工程领域的运用已经有较长的时间,它在岩体质量验收、灌浆质量检测、爆破控制校验等方面具有独特的优势,因此成为工程技术人员颇为青睐的勘探手段.但是由于测试人员对声波测井技术原理不清楚以及测试流程不规范等原因,导致声波测试过程中出现与常理相悖的测试数据异常问题.这些问题的存在,对获取岩体质量信息造成了一定的干扰,同时也给声波测试资料的可靠性带来质疑.本文结合具体工程中的实测声波资料,针对常规岩体单孔声波对比试验获得的波速曲线中存在的整体性异位或升降等异常现象,通过对比不同试验阶段的声波测试曲线,阐述单孔声波对比测试曲线异常的具体表现及典型特征,分析产生测试异常的主要原因,并提出相应的解决方案或措施.研究结果表明:声波对比测试异常实质上是试验操作不够规范的问题,其中对比声波曲线的整体性异位主要是由采样偏差造成,属于线性系统误差,可以通过增加对比单元长度、提高岩体重合率等措施进行补救处理；而声波曲线的整体性不均匀升降则与耦合流体的纯度有关,属非线性系统误差,难以进行补救校正,因此规范测试流程是避免出现该类异常的唯一途径.本成果为运用声波测井技术解决相关问题时避免或消除声波对比测试异常提供了参考和借鉴,具有重要的工程指导意义.
