Quality Assessment of Dry Jet Mixing Pile Shaft of Cement Soil

摘要

Study on quality of Dry Jet Mixing Pile Shaft of cement soil was mainly discussed the pile quality inspection. As one of deep foundation mixing methods, Dry Jet Mixing Method of cement soil was widely used in those large constructions such as the Jinzhu highway and the Jinjiu railroad as well as the Huning super railroad, China, etc. Work experiments herein were analyzed and summarized, and current studying situation of the dry jet mixing technology in China was described. The reasons why uneven quality of the pile shaft has occurred were more detailed analyzed and described associating with the several history cases from the stabilization theory, construction methods and inspection ways of Dry Jet Mixing Method. Conclusion can therefore be made respectively to provide references to study and the further engineering application.
