| 中文摘要: |
| 堆填方式和堆填时间决定了人工填土的工程性质,其直接影响到填土的均匀性、密实度和是否具有湿陷性。对填土的岩土工程勘察应结合实际情况采取多手段进行,野外采取原状土样进行室内土工试验,野外原位测试包括静力触探试验、标准贯入试验、圆锥动力触探等方法。依据规范综合判定出填土的工程性质,确定出填土能否作为地基持力层,或者对填土地基进行适当处理。 |
| 英文摘要: |
| Engineering properties of artificial fill are decided by filling methods and filling time, and also have an effect on homogeneity and compactness of the fill and whether the filling soil is collapsible. Multiple measures can be taken in the geotechnical investigation of the artificial fill based on the real condition. For the original soil sample from the field, we can rake indoor soil test, field in-situ tests include cone penetration test, standard penetration test, dynamic penetration test and so on. The engineering property of filling soil is decided according to the criterion, and determine whether the fill can be used as a foundation bearing layer or the land filling base should be disposed by taking some proper methods. |
