| 摘 要： | 由于基坑变形是多因素作用的结果,而其变形系统的实质是一个灰色系统,所以可以采用灰色系统理论对基坑变形进行预测.根据灰色系统理论,建立了基坑变形的GM(1,1)预测模型,并利用某工程的实际监测资料对未来基坑变形进行预测,结果与实测值吻合较好,证明了该预测模型具有较好的精度,对指导基坑工程的信息化施工有积极意义.

| Abstract: | Because the deformation of foundation pit is caused by the effect of many factors,and the deformation system of foundation pit is essentially a grey system,so the deformation of foundation pit can be predicted by the grey system theory.According to the grey system theory,the grey prediction model GM(1,1) for deformation of foundation pit is established,and the later deformation of foundation pit is predicted by the field monitoring data of a project.The prediction results conform to the observed value.It is... |
