| 摘 要： | 通过对卵石地层的结构进行深入分析,认为其所具有的特殊结构会产生"粘聚力"的效果。同时,通过对卵石地层进行原位剪切试验,其测试成果"粘聚力"不等于0,且数值显著,由此,进一步证明需对卵石地层的"粘聚力"进行重新认识、合理取值。

Discussion and Veri cation about the Pebble Stratum Cohesive Force and in-situ Shear Test Results |
| |
| Abstract: | Through in-depth analysis the structure of pebble stratum, it is thought that the special structure of pebble stratum will produce the effect of “cohesive force”. At the same time, the in-situ shear test was carried out in the pebble stratum, and the test result shows that the cohesive force is not equal to zero, but with a significant value. Therefore, the “cohesive force” of pebble stratum is needed re-understanding and giving reasonable values. |
