The use of statistic analysis in predicting of ground and wall movements in soft clay

This article presents the results of analyses on the effective factors of wall and ground movements, using the measured data collected > 40 propped wall cases from various deep excavation in worldwide sites with soft clay conditions. In this paper we analyses data with Minitab a statistic analyzing software that can analyze data and give good information like correlation coefficient and cluster analysis of factors and Regression analysis. The calculated presents that there are not signification correlations between excavation depth, the system stiffness, and factor of safety against base heave of excavations, Support spacing and ground and wall movements contrary to other researches but there is signification correlation between maximum vertical settlement and maximum lateral movement. Results show delta boolean AND(2)(hmax) = 150 delta(vmax) (mm).
