METHOD TO DETERMINE DEPTH IN LANDSLIP-HAZARDOUS ROOT MASSIF OF POTENTIALLY DEFORMABLE HORIZON

摘要

FIELD: construction.;SUBSTANCE: method to determine depth in landslip-hazardous root massif of potentially deformable horizon by detection of horizon with minimum ratio between values of vertical pressure at horizon at the slope section near foot of landslip-hazardous root massif - actual and critical, includes detection of inner friction angle, angle of adhesion and specific weight of soils, measurement of height of slope of landslip-hazardous root massif and height of slope, to increase accuracy of detection of depth in landslip-hazardous root massif of potentially deformable horizon, borders are detected for zone of location of potentially deformable horizon, in zone of location of potentially deformable horizon for each intermediate i horizon with depth HZ_ih+H at slope area near foot of slope of landslip-hazardous root massif the following is determined: values of vertical pressure at i horizon: actual value, critical value and their ratio, minimum value K_i=K_min is set, and depth of potentially deformable horizon is detected using mathematical dependence.;EFFECT: early detection of potentially deformable horizon in landslip-hazardous root massif, where main surface of landslip sliding is formed, as massif stability is disturbed.;2 cl, 2 dwg
