                      摘要:
                      研究基于無側限抗壓強度試驗的方法,測定種植在長51.0 cm、直徑110.0 mm、厚3.2 mm的PVC管內的非洲狗尾草、鴨茅和紫花苜蓿3種草本植物根土複合體和素土的黏聚力(C),初步探討了黏聚力增量(ΔC)與破壞面上根面積比(root area ratio,簡稱RAR)、根系平均抗拉強度(Tr[TX-])的相關性;運用Wu & Waldron模型對3種草本植物根系提高土體抗剪能力進行預測。結果表明,非洲狗尾草、鴨茅、紫花苜蓿在0~25 cm深度範圍內的ΔC值分別是4.75、4.04、1.39 kPa;在25~50 cm深度範圍內的ΔC值分別是3.1、2.32、0.71 kPa。紫花苜蓿的ΔC值與破壞面的RARTr[TX-]相關不顯著;非洲狗尾草、鴨茅的ΔC值與破壞面的RAR顯著相關,與Tr[TX-]不相關。Wu & Waldron模型預測的非洲狗尾草、鴨茅、紫花苜蓿根系提高土體抗剪能力值分別是實測值的60.08、50.9、179.08倍。
