Abstract：The reinforcement of cement soil in the passive zone plays an important role in strengthening the embedding and controlling the deformation of the supporting pile.At present，various software for the passive zone is to solidify itas asoil layer according tothe elasticresistance method tocalculate，soit is necessary to determine the m value and k value of the reinforcement zone.In the existing specification，the value of m for the reinforced soil is uniformly taken as 6000kN/m4 ，and the general soil layer in the finite soil is still selected according to the same empirical formula of the semi-infinite soil，which notonly calculates the dimensions before andafterthe inconsistency， but also ignores the superposition of the earth pressure inthe pasive zone under the finite soil.The selection of k valueandmvaluein the foundation pit elastic resistancemethod under theconditionoflimited soilinreinforcedsoil and general soil is studied，and the k value solution method based on the elastic modulus of soil layer is obtained.

Key words： passive area reinforcement；m value；Hookes law；elastic modulus； elastic resistance method
