【Abstract】：Inordertoanalyzes theconstruction effctofdrywetcement soil mixing pilesunderdiferent plastic states， this paper focuses on thecement-soil bidirectional mixing pilesused during the Lianyungang-Huai'an section expansion project of the Changshen Expressway project.It analyzes and evaluates the test pile data for both dryand wet mixing pile construction methods，considering the diferent plasticity states of thesoft foundation soil in various sections.A comprehensive scoring method is used to evaluate the testpile results，verify construction technical parameters，and，based on the evaluation results，propose selection standards for dry and wet mixing methods.

【Key words】： cement-soil mixing piles；plasticity states；weak foundations
