                            用途

                            土的靜止側壓力系數KO,是指單元土體在無側響應變(εх=εу=0)條件下,有效側向壓力σ3(或稱小主應力)與有效豎向壓力σ1(或稱大主壓力)的比值。計算公式為KO=σ3/σ1或KO=⊿σ3/⊿σ1。

                            主要技術指標

                            1、土樣面積30㎝2(土樣直徑Φ61.8㎜)。

                            2、土樣高度40㎜。

                            3、σ3=0-600kPa。(精度小于0.3%)

                            4、σ1=0-800kPa。(精度小于0.3%)

                            5、ε1最大為20%,即最大豎向變形8㎜

                            6、上下透水石的滲透系數不小于n×10-3㎝/s壓力腔乳膠隔膜應透明,防老化,厚度約為0.4~0.5㎜。

                            7、加荷裝置

                            最大出力8KN,最大位移80㎜,最小加荷速度0.001mm-4mm/min(加荷速度根據用戶或實驗需求自己設置)。
