　　复合土钉支护结构在基坑支护工程领域有着越来越广泛的应用。支护结构在使用的过程中涉及到很多方面的影响因素，各种因素对支护结构体系的影响往往具有不确定性，即具有灰色特性。本文通过将非等间隔时序Verhulst灰色模型应用到预应力锚杆复合土钉支护的实际变形预测中，发现在对常规灰色Verhulst模型采用傅里叶函数进行残差修正以后，模型的预测分析效果可以得到较好的提升，可考虑将傅里叶变换用于Verhulst模型修正。在复合土钉支护的位移变形的应用分析中具有一定的参考指导价值。

Compound soil nailing structures are becoming more and more widely used in foundation pit retaining engineering field. Supporting structure will be affected by many kinds of influencing factor, the influence of these factors is uncertain, means it has the gray character. This article tries to apply the unequal interval gray Verhulst model to the deformation forecasting of prestressed anchor compound soil nailing retaining structure, discovered this theory model has a preferable analysis effect after its definite residual correction with the Fourier transformation, Fourier transformation can be considered in using of Verhulst model correction. It will provide some reference in the using of compound soil nailing retaining structure deformation forecasting.
