isaki

Study and application of biolngical oil displacement agent in cementing pad fluid
生物驱油剂用于固井前置液的研究与应用
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
在三维有限元计算中，对不同工况（沉井充填、锚体浇筑、主缆架设、箱梁吊装、桥面铺装以及通车运营）下的施工过程作了模拟，全面揭示了各工况下锚碇沉井基础与地基土的变形变位规律，着重分析了影响散索鞍水平位移的因素以及不同工况下沉井前测地基土水平向抗力变化规律，并提出了不同深度地基土水平向抗力与水平位移间的拟合关系。
