| 中文摘要: |
| 建筑场地抗震设防烈度为7度及以上时,地基土为饱和砂土和饱和粉土,应进行液化判别,存在液化土层的地基,应根据建筑的抗震设防类别、地基的液化等级,结合具体情况采取相应的措施。地基的液化等级为中等、建筑抗震设防类别为丙类时,可采取挤密碎石桩部分消除地基液化沉陷。当经挤密碎石桩处理后地基土为轻微液化时,按照规范,对于抗震设防类别为丙类时,可不用采取抗液化措施。抗液化措施采取部分消除地基液化,解决了地基土的液化问题,对工程也相对比较经济和合理。 |
| 英文摘要: |
| Liquefaction discrimination should be done if the seismic precautionary intensity of the building site is 7 degrees and above and the foundation are saturated soil & saturated sand. If the foundation has liquefaction soil, we can take corresponding measures according to the seismic precautionary intensity or liquefaction lever . In the case of liquefaction lever is medium and seismic precautionary intensity is C class, sand-gravel columns can be used to eliminate liquefaction settlement. If foundation soils are slight liquefaction after sand-gravel columns, anti-liquefaction measures needn’t to be taken in case of seismic precautionary intensity is C class according to the codes. Liquefaction of foundation soil is settled by the anti-liquefaction measures of partial elimination of foundation liquefaction .It is Economic and reasonable for the construction engineering. |
