求翻译：建立连续梁桥的实体模型，在支架立杆对应的位置设置非线性弹簧，通过非线性弹簧考虑由于地基沉降和支架间隙等引起的非弹性沉降、支架体系弹性压缩变形和零抗拉刚度。是什么意思？

Establishment of continuous beam bridge of solid models in nonlinear spring bracket corresponds to the upright position, by nonlinear spring and support gap due to ground settlement caused by settlement, scaffolding system elastic compression inelastic deformation and tensile rigidity of zero.
