摘要
基坑开挖施工必然会引起基坑的稳定问题,以及支护结构的变形和周围地表的沉降问题.采用灰色系统预测理论建立了深基坑变形的GM(1,1) 预测模型,以基坑附近地表沉降量为指标,利用某工程实例的实际观测资料对基坑以后的变形进行预测,结果与实际值吻合较好,证明了该法的可行性.
Deep excavation always causes problems of stability of the deep pit,and deformation of the bracing structrue as well as the ground nearby.The prediction model for deformation of deep excavation is suggested according to the Grey System theory.Using ground settlement as index,an engineering case is analysesed.The prediction result conform to the observing result. It proves the model is feasible.
