Method:Selecting the best performance parameters of the instrument by using orthogonal design,investigating the influential factor of hydride generation,examining the limit of detection and quantitation,linearity and range,sensitivity,accuracy and precision,and comparing to the diethylamino dithiocarbamate silver(DDC-Ag)method.

The reason of the collapsibility not to be eliminated entirely shows that the dampness of soil and the compaction energy have important influence on the effect of DDC pile in ground treatment .
