Computing method for pressure of cement soil mixed material replacement cushion

The invention discloses a computing method for pressure of a cement soil mixed material replacement cushion. The method comprises a cushion layer, a first pressure box, and a second pressure box. The first pressure box and the second pressure box are respectively arranged on two ends of the cushion layer. Compared with lime soil whose mechanical characteristic is similar to a cement soil mixed material, the cement soil mixed material has relatively higher foundation capability. At present, in practical engineering, a standard value of maximum foundation soil bearing capacity of 1:9 cement soil is 230 kPa, and the bearing capacity is amount to 3:7 lime soil level. The cement soil mixed material has good stress diffusion ability, and the stress diffusion ability is little influenced by replacement thickness, and the cement soil mixed material has relatively low requirement on substratum foundation soil bearing capacity. 本发明公开了种水泥土混合材料换填垫层压力的计算方法，包括垫层、第压力盒和第二压力盒，所述第压力盒和所述第二压力盒分别设置于所述垫层的两端。本发明水泥土混合材料与其受力特性相似的灰土相比
