Discussion about Reasonable Utilization of Liquefaction Soil Layer |
| |
Abstract: | By analyzing the mechanism of sand and water spewing of the liquefiable foundation soil with non liquefiable soil layer above under the effect of foundation,the author of this article advances a method to judge if the foundation soil,which is determined to be liquefiable soil according to code for seismic design of buildings,can be used as the bearing stratum directly. |

Keywords: | excess pore water pressure sand and water spewing spewing pressure vertical additional stress liquefiable soil. |
