Abstract:Total thrust on shield tunneling machine is the most important mechanical quantity, while its also the core parameter which can reflect the geological adaptability of the shield. Mechanical model of total thrust is established by applying the mechanical analysis firstly. Multiple regression method is applied to indentify undetermined coefficients of mechanical model. Based on the on-site data acquired from Rd. TieDong to Rd. ZhangXingZhuang of Tianjin No.3 subway project, regularity and compositions of model r… Show more
