| 摘 要： | 采用简化模型,通过改变模型开口处土工布的渗透系数,对真空预压加固软基过程中加固区地下水位的变化情况进行室内试验模拟,得到真空预压过程中地下水位下降的结论.同时拟合试验数据得到H-(-1gK)曲线,可知土体的渗透系数越小,加固区水位下降值越大.试验表明:真空预压加固软基时应考虑周边地下水对加固区域的补给,并需对加固区周边密封设计制定出新的标准. |

| Abstract: | Applying the simplified model and changing the permeability coefficient of geotextile at model openings,this paper simulates the actual changes of underground water level at treatment interior area during soft ground treatment by vacuum preloading based on the laboratory test.The test results show that the underground water level declines during vacuum preloading.Fitting the curve of H-(-lgK),it is concluded that the less the soil's permeability coefficient is,the greater the water level declines.The test r... |
