Abstract On the basis of time series analysis of diaphragm wall deformation in deep pit system，a MATLAB system-based ANN multi-step deformation forecast model is developed. The deformation corresponding to multi-steps of excavation can be predicted with this model at a time，and the construction parameters can be adjusted in time，so that the diaphragm wall deformation can be controlled. The deep foundation pit of north anchorage of Runyang Bridge is taken as a case example to make study on intelligent forecast and control of construction deformation，and it is showed that the results of prediction agree well with the data of in-situ measurement.
