| 摘 要： | 采用原位直剪试验、室内直剪试验等测试手段，运用最小二乘法、优定斜率法等数理统计方法，对机场高填方压实土的抗剪强度特性进行了分析．试验结果表明，对于大型复杂的场区，应采用多种试验方法来综合确定强度参数；水对填土的抗剪强度影响相当大，含水率越大，强度值降低越多；高填方土体应注意高应力作用下抗剪强度的变化；压实度影响填筑体的强度高低，但压实度λc与强度指标C和Ф的定量关系有待进一步研究．

| Abstract: | With the in-situ and indoor direct shear test,the least-square method,majorized inclined-ratio method and other mathematic statistics,shear strength properties of high fill and compaction soil of an airport are studied.The results of tests show that: it is needed that varied tests are employed to quantify reasonably shear strength parameters;water influences the values of shear strength largely,higher water content causes lower values of shear strength;many attentions should be paid to the varieties of shear strength under high stress of high fill and compaction soil;degree of compaction effects the shear strength,but the quantitative relations between degree of compaction and shear strength parameters are remaind to further study. |
