ANALYSIS OF PARALLEL DRAINS FOR HIGHWAY CUT-SLOPE STABILIZATION

Methods of analyzing parallel drains for highway cut-slope stabilization are introduced. The analysis procedure is based on the prediction of the phreatic surface location within a soil mass under steady-state seepage. Relative effectiveness of alternate drain spacings is determined by estimating the steady-state phreatic surface at a profile located midway between drains and by using analysis procedures for the design of parallel drains in agricultural field drainage. Applications are made to seepage from an infinite-slope source. Mathematical analyses for estimating steady-state phreatic surfaces at a blanket drain and cut-slope intercept with an infinite-slope seepage source are also introduced. An illustrative design problem is worked out in detail. /Author/
