การวิเคราะห์หาปัจจัยที่ทำให้เกิดเหตุการณ์ความเสี่ยงในงานก่อสร้างระบบป้องกันดินพัง

Abstract

Underground construction is one of the most risky parts for high-rise building construction. Typically this type of work is found to be more complicated and riskier than that of superstructure. The challenge commonly encountered in underground construction is the ground movement causing damages to adjacent buildings. This research attempts to identify risk factors found in the construction of a two-layers-bracing sheet pile wall soil protection system. A Model has been developed to predict the possibility of adjacent buildings being damaged by operation; Outcomes from different scenarios of risk factors were gathered from experts in this field. The Logistic Regression method has been used to generate coefficients associated with each risk factor. The method is simple and can be used to produce useful information which is difficult to obtain in real-life constructions.
