Abstract Research purposes: Application of flat dilatometer test ( DMT) in Geotechnical Engineering is quite a lot． However，how to use it to obtain soft soil foundation bearing capacity has to be studied． The paper studied on how to obtain soft soil foundation bearing capacity through DMT using in － situ tests data．
Research conclusions: Relying on in － situ tests of Shangqiu － Hangzhou high － speed railway，the paper studied the comparison and analyzed the correlation between dilatometer modulus ED and static cone penetration test Ps and vane shear test Su，then obtained the calculation formula of soft soil foundation bearing capacity through DMT，fak =0． 019ED +15( ED≤5 000 kPa) ． Calculated results were compared with other tests and DMT reflected soft soil foundation bearing capacity better．
