| 摘 要： | 黏性土地基中存在潜水,对地下结构物有浮力作用,在考虑浮力问题时抗浮水位是否折减及折减多少关系到是否采取抗浮措施和工程造价、施工工期等问题.为此,结合具体工程在现场进行了原位测试.试验结果表明,可以取折减系数为0.85,按此计算则不必采取特殊的抗浮措施,节省了工程造价和工期. |
| 关 键 词： | 抗浮折减系数 原位测试 孔隙水压力 地下水浮力 |

| Abstract: | Phreatic water in cohesive soil, we must consider the buoyancy effect for underground structures. In con- sidering buoyancy, whether water level for prevention of up - floating should be reduced or not and how much should be reduced, this concern anti - buoyancy measures, construction costs, construction period etc. For this reason, in - situ test has be proceeded with specific project. Test result demonstrates reduction coefficient can be the O. 85, Ac- cording to the calculation, anti - buoyancy measures whould be not necessary, and save the construction costs and construction period. |
| Keywords: | anti - floating reduction coefficient in - situ test pore pressure groundwater buoyancy |
