During the 3d finite element calculation, try to simulate different procedure of the construction ( like sunk well in - filling, main cable erection, box girder hoist, bridge flooring and opening to traffic ). and then, reveal the regulation of deformation and displacement on the foundation and soil during different period. after got these, this thesis put great attention on the analysis of the reason which cause the horizontal displacement of the cable saddle, as well as the regulation of the pressure ' s changing in the soil located on the front side of the sunk well foundation
在三維有限元計算中,對不同工況(沉井充填、錨體澆築、主纜架設、箱梁吊裝、
橋面鋪裝以及通車運營)下的施工過程作了模擬,全面揭示了各工況下錨碇沉井基礎與地基土的變形變位規律,著重分析了影響散索
鞍水平位移的因素以及不同工況下沉井前測地基土水平向抗力變化規律,並提出了不同深度地基土水平向抗力與水平位移間的擬合關系。
Through the calculating example results and the comparisons with other calculating theories, it is proved that the calculating formulas of the combined geometry curve theory is valid, practical and accurate. it can be used in the calculation of line shape at the preliminary design, and can meet the engineering need. ( 3 ) this thesis researches systemically on the calculating theory of the suspension bridge ’ s cable system, including calculating design line shape and internal force, erection line shape of cable and pre - displacement of saddle without loads, the fixed position for erecting cable and amendatory method of cable ’ s unstressed length
