説明
Based on the results of field measurement of physical and mechanical properties of hillslope materials in granitic mountains, the angle of shearing resistance (φsat, degree), the cohesion (Csat, gf/cm2) and the hydraulic conductivity (K, cm/sec) of grus under saturated water content were deduced by two parameters of unit weight and grain size of soil as following regression equations :<br>φsat=22.2γdCC0.0625+9.5(R2=0.71)<br>Csat=133.6γd-55.7CC2.0-100.0(R2=0.75)<br>log10K=-1.512γdCC2.0-0.211(R2=0.79)<br>where γd is the dry unit weight of soils (gf/cm3) and CCD is the content for coarser grains than D mm. Since the values of CC0.0625 and CC2.0 can be easily measured by sieving method and γd is estimated using simplified dynamic cone penetrometer, these parameters can be estimated using the above equations at many points and depths of the soil layer on steep mountains.
