Abstract Abstract : Research purposes : Static lateral pressure coefficient is indispensable important parameter in metro design， which can make the design measures properly With its accuracy，and it also can ensure the subway construction safety and economy. Relying on the geotechnical engineering practice in Tianjin metro, the access method and test data of the static lateral pressure coefficient are analyzed，the advantages and limitations of different means are summarized，and the appropriate metiiod of tiie static lateral pressure coefficient is discussed. Research conclusions :( 1 ) The flat dilatometer test ( DMT) is suitable for the shallow strata to obtain static lateral pressure coefficient，the lateral pressure test is generally larger，and laboratory test is smaller； (2) Any single way to obtain the data are not comprehensive and reliable， it must adopt a comprehensive method to determine reasonable design parameter； (3 ) The research results can provide reference and reference to obtain the soil static lateral pressure coefficient for t!ie subway of geotechnical investigation in Tianjin and similar areas.
