In order to study the characteristics of relativistic Langmuir solitons, the control equations of relativistic strong Langmuir turbulence in ultrapowerful laser plasma were obtained from momentum theory. And then, theoretical analysis was made. The research shows that half-width of wave-packet will become narrower and the total energy and momentum of solitons will become bigger with the increasing of average Lorentz factor of electrons and turbulence parameter of field. The relativistic effect of electrons affects the total energy and momentum of the solitons much larger in the nonlinear part than in the linear part. The results will provide the theoretical reference on the nonlinear phenomenon in ultrapowerful laser plasma.
