灰色理论预测沉降在软基加固中的应用

在软基上修筑路堤，减少软基土的不均匀沉降是工程实际的切实需要。因此，提高沉降计算的可靠度是十分重要的。但是用传统的固结理论分析方法求解的沉降值，不能完全符合实际情况。将GM(n，h)灰色理论模型应用于沉降预测中，并与实测值、理论公式、经验公式计算值进行对比总结，灰色模型计算结果与实测值吻合较好，而理论计算结果较实测值大。由此给出了采用《规范》法求最终沉降量时的建议值，以期确定出一个较合理、适用的修正系数。

Application of grey theory in soft soil settlement predication

The uneven settlement should be avoided in soft soil when the subgrade is built. It is very important that the degree of reliability for settlement calculation be improved. However, the practical engineering situation doesn't tally with the calculation settlement based on traditional consolidation theory. Using grey theory GM(n,h) model we calculate the settlement and compare the monitoring settlement with the calculation settlement,the result is identical with the value of monitored. A more reasonable and applicable correction coefficient is suggested .
