Initially, the soil model and parameters of soil and structural elements were calibrated with a well-documented deep excavation case, namely TNEC excavation, by using PLAXIS 2D. Then, 384 sets of hypothetical case, with variation of influence factors such as excavation depth, excavation width, normalization undrained shear strength, the system stiffness of the wall, and the axial stiffness of the lateral strut per unit length of the wall, were simulated in order to establish the relationship between the maximum wall lateral deflection and those factors. The multivariate regression analysis with exponential model was selected as a proper model for processing those data. Owing to some data were illogical from practical point of view, only data from 358 sets of hypothetical case were considered as valid data. The SPSS software was used as a tool for data processing. Finally, a simplified method was developed. The result was compared and discussed with the previous proposed methods. Chang-Yu Ou 歐章煜 2015 學位論文 ; thesis 217 zh-TW |
