Description |
VERSAT-BlockWall provides design calculation of a segmental block retaining wall, including factors of safety on sliding and overturning for each block on the wall. Maximum pressure at the base of each block is calculated using two methods, i.e., the Meyerhof method and the method assuming a triangular distribution of base reaction. Base input parameters include size/weight of blocks and its arrangement, inter-block friction angle and base friction angle, wall/soil friction, wall inclination angle, and backfill soil unit weight and lateral pressure coefficients (Ka or Kae), which may be obtained in advance using VERSAT-KaKp. In addition to a triangle distribution of lateral soil pressure, the calculation module also allows for a trapezoid distribution especially for simulation of seismic soil pressure where soil pressure is non-zero at the wall top. The web page includes a force diagram for the segmental block wall, and all equations used in the calculation can be downloaded on the web page through the tab Download Calculation Note. The analysis is carried out on the web server. It does not require a computer to run the program; instead it only requires an Internet browser to setup input and display results. |
