【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

水泥土攪拌樁常用于軟土地基深層加固將水泥與土體充分混合，通過物理和化學(xué)反應(yīng)增強(qiáng)土體的強(qiáng)度，從而提高地基的承載力與穩(wěn)定性。（剩余4511字）
