吹填软土结构强度形成及灰预测

摘要

Through designing different drainage tank the paper studied different drainage conditions and time effects on structural strength formation of soft dredger fill, and carried out grey prediction. The test results showed that when the drainage paths didn't block, the free water of the soil was fully discharged, the structural strength formation was faster. In the same drainage conditions, the structure strength grows correspondingly with the time ,faster in the early, later stabilized. Grey prediction can be used to predict structural strength formation of soft dredger fill in short-time, it gives reference to engineering practice.%通过设计不同排水条件的实验槽,研究了不同的排水条件及时间效应对吹填软土结构强度形成的影响,并对实测结果进行了灰预测.试验结果表明:排水路径畅通时,土体中自由水得到充分排出,结构强度形成较快;在同一排水条件下,随着时间的增长,结构强度相应增长,前期增速快,后期基本趋于稳定.灰预测可以用来对吹填软土结构强度形成进行短期预测,值得工程实践参考.
