Modulus of Subsoil Reaction According to Chadeisson
Based on the measurements on sheeting structures in different soils and computation of a displacement of the structure needed to mobilize the limit value of passive pressure R. Chadeisson (1961) and A. Monnet (1994) derived expression for the determination of the modulus of subsoil reaction in the form:
where: | EI | - | bending stiffness of the structure [kNm2/m] |
γ | - | unit weight of soil [kN/m3] | |
Kp | - | coefficient of passive earth pressure [-] | |
K0 | - | coefficient of earth pressure at rest [-] | |
c' | - | effective cohesion of soil [kPa] | |
Ap | - | coefficient of influence of cohesion (1 - 15) [-] |
