Calculation of Building Settlement Induced by Deep Excavation Under Seismic Loading

The present article describes a procedure for predicting the settlement of structures surrounding deep excavations in Vietnam that takes the technological settlement component into account. In this study, correction factors were established for a formula designed to calculate the excavation-induced settlement of buildings having strip foundations under seismic loading when factoring in the presence of soft saturated soils, which can be used in risk assessment during building operation. In addition, a developed procedure for determining the maximum force acting on a slurry wall taking seismic loading into account is presented. The calculation results obtained using the proposed procedure exhibited satisfactory consistency with those acquired as per EC8 and TCVN 9386-2012 (Vietnam). Finally, the comparison of predicted settlements with geotechnical monitoring data confirmed the possibility of applying the proposed procedure for calculating settlements.
