灰色系统理论在预测单桩承载力中的应用

Applying Grey System Theory in Forecasting the Carrying Capacity of Individual Pile

通过对一定数量的不完全的静载荷试验数据进行累加或累减处理.用特定的函数逼近拟合,建立灰色微分模型（如GM（1,1）模型）.预测桩顶沉降随荷载增加的变化趋势,达到推测预定沉降所对应的荷载值或预定荷载下沉降值的目的.

Using grey system theory to forecast the carrying capacity of individual pile is a very effective method. Accumulated adding or subtracting a quantity of and incomplete data from the static fore test, then draw up them with especial function, there could erect grey differential coefficient model, such as, the model GM（1,1）. In order to forecast load value with the engaged sedimentation or the sedimentation value with engaged load value, need forecast the change trend of the sedimentation on the top of pile under the unceasing add load.
