In order to analyse the intension and stability of the double-row-pipe frozen soil wall in the deep thick alluvium,regarded temperature field of the frozen wall as the trapezoidal-shaped distribution. Basing on the relation of mechanical characteristics of frozen soil wall and temperature, with Druker-Prager strength criterion, deduced the analytical expression of stress of frozen soil wall’s elastic zone and plastic zone . The results showed that: the radial stress increases with the relative radius r, The change of hoop stress in the interval I, II, III with the relative radius of r was different.The load of frozen soil wall had nothing to do with the stress of plastic zone of freezing wall.In addition, according to the engineering example ,the load of control layer of the frozen wall was far less than its plastic limit load ,which meaned the frozen soil wall was safe.
