摘要
着重讨论了放射性同位素法在测定路基土压实度时经常遇到的含水量偏值估计问题。分析了偏值存在的原因及进行偏值校正的前提条件，并且给出了偏值估计的计算方法。
The paper discusses the moisture bias
estimation problems which often exist in measuring of relative compactibility of roadbed soil
materials by radioisofopic density instruments. The author analyses the causes for the bias
existence, and sums up the premiss for the bias correction, and finally presents the calculation
method to estimate the bias.
