    in determination of the active earth pressure of strip load surcharge, we would always do elastic supposition, and for that, we used boussinesq. in this essay, by supposition of plastic environment of the earth, a new formula was presented for the effect of strip load surcharge on the wall. in this new formula, effects of gradient, and the friction angle between earth and wall, and gradient of the wall, and friction angle of earth, is considered. in this essay, by matlab software, a program is presented for calculation of the pressure on the wall in different situations of setting strip load surcharge. also this essay considers the distance of the effect of strip load surcharge, and by mean of that, we can determine the length of the surcharge and the distance of surcharge from wall which has taken effects from the imported pressure. it should be pointed out that imported pressure totally consists of earth pressure and surcharge pressure. this essay expresses the considered stress distribution, under the effect of strip load surcharge on the wall having the effect of the earth behind it. and dependent on the situation of strip load surcharge, we present four kinds of distribution.
