| 摘 要： | 利用建筑工程静力触探资料,对相关距离的各种计算方法进行了对比研究;研究了取样间距对相关距离计算的影响;探讨了利用剪切波速计算水平向相关距离的可行性。通过不同土性指标相关距离对比以及同一指标相关距离竖直向与水平向对比,研究了土性指标相关距离的性状。总结了太原和杭州典型土层相关距离的地区资料,并结合某一工程实例讨论了相关距离的贝叶斯估值方法。研究表明,利用静力触探试验曲线计算竖向相关距离是一值得推荐的途径;利用剪切波速计算水平向相关距离是完全可行的;相关距离的计算要密切关注取样间距的影响;不同指标相关距离具有很好的一致性,同一指标相关距离水平向性状远大于竖直向性状;土性指标相关距离具有横观各向同性。 |
| 关 键 词： | 土性指标 相关距离 静力触探试验 剪切波速 |

| Abstract: | The characteristics of correlation distance on soil properties indexes are studied in the paper. Different methods to calculate the correlation distance are compared with a large number of calculations, it is according to the static penetration data of some projects. The influences of shear-wave velocity on the calculation of correlation distance are considered, it is feasible. The study shows that the static penetration curve is most useful way to calculate the vertical correlation distance, the shear wave velocity is used to horizontal. At same time, some useful conclusions are obtained. |
| Keywords: | soil properties indexes correlation distance static penetration test shear wave velocity |
