Webon retaining structures. The dependence of the coefficient of lateral earth pressure on the strain increment ratio was studied and on the basis the formation mechanism of earth pressure was discussed by Zhang et al. (1998). Lateral strain parameter R is used to represent the lateral deformation of the soil, which is caused by the wall displacement. Weband 40° with an increment of 5° and the results are shown in Fig. 4. Note that contours of constant roughness coefficients, C,, are also drawn in Fig. 4 for ease of application.
