Intelligent prediction on deformations in the construction of anchor block-abutment foundation of an extremely long-span suspension bridge (Runyang Bridge over Yangzi River)—a case history study

On the basis of soft science theory used in the field of geoengineering projects, a MATLAB system-based integrated ANN multi-step deformation prediction in construction has been developed. The study of a deep excavation work-North anchor-block abutment ( foundation ) of the Runyang suspension Bridge reveals that the results of prediction have a good agreement with the monitoring data during insitu measurement. The prediction work ensures the safety under construction and safeguards the environment nearby excavation work .Thus , the study in this article proves that the method suggested here is feasible for deformation prediction in such excavation construction work . This article gives a brief presentation in the form of a case history study.
