Abstract
As a technical means to directly obtain underground engineering information,in-situ testing methods play a key role in engineering investigation.In order to obtain the bearing capacity of the surface soil foundation in the construction site of a water supply station,the static cone test,the cross plate test and the standard penetration test were carried out,and the accuracy and ease of operation of different in-situ test methods were compared,and the results showed that the characteristic values of the bearing capacity of the foundation obtained by the static cone penetration test,the cross plate test and the standard penetration test were 93,94 and 96 kPa,respectively,which were small and close to the indoor test(100 kPa)and the recommended value(90 kPa).All of them have a certain representativeness and reliability,which en-sures the smooth progress and quality of the project,but in the actual project,it is necessary to comprehensively consider the project cost,op-eration difficulty,on-site equipment and other factors to comprehensively select the appropriate in-situ test method.关键词
