Abstract: The paper discusses the ergonomics problems about eye height, operating handles, bottoms etc. in machine tool design. Points out the misapprehension of human body average dimension, gives some constructive design data according to different human body dimension percentage to design different operating elements. It can be the reference for designers in machine tool industrial.

Abstract: The prediction of deformation of foundation pit’s supporting structure is the basis of construction control of deep foundation pit. Meanwhile, it is vital to the safe excavation of foundation pit. In the work, the 1st project of Huaqiao in Jiantao Square of Kunshan City is chosen. Besides, model of combination based on entropy method is built to predict the displacement of circle beam with BP neural network and ARMA time series model. Finally, the analysis shows that combination models improve overall prediction on the premise of better predicting accuracy. Thus, it is of practical value.
