Analysis for the internal force of pile capping beam considering continuity of soil mass 考虑土体连续性的桩基承台梁内力分析
The design and construction of obliquely supported high bent for pier cap beams of lu pu bridge 上海卢浦大桥墩柱盖梁斜撑高排架的设计和施工
Due to the complexity of the behavior of pile capping beam widely used in the construction , the inverted continuous beam method is usually adopted in design methods to simplify the computation 条形桩基承台梁在我国现代建筑工程中应用极为普遍,其设计计算大多采用倒置的连续梁模式进行简化计算。
Based on the detailed investigation , the distribution of cracks in capping beam of the abutment of huaihe river bridge on the national road 107 is presented , the causes leading to the cracks are thoroughly analyzed , and the construction scheme and methods for remedy of the cracks in the abutment are described as well 摘要在详细调查的基础上,介绍了107国道槐河大桥桥台盖梁裂缝的分布情况,深入分析了裂缝形成原因,并阐述了该桥的加固方案和施工方法。
Consequently , on the basis of non - winkler foundation model , a finite - element method that utilizes foundation flexibility matrix into iterative calculation is proposed in this paper originated from the item " the optimal design theory and research of pile capping beam " sponsored by natural science fund of hunan province , which the continuity of soil mass can be accounted for under various boundary conditions , different loadings and irregular beam characters 本文结合湖南省自然科学基金项目“桩基承台梁优化设计理论与方法研究” ,针对非文克尔地基(半空间、线性变形层或单向压缩层地基模型等)上的桩基承台梁,提出一种利用地基柔度矩阵来进行迭代的有限单元法,可充分考虑梁下土体的连续性,并对基础与土体脱开、承台梁截面变化、梁体边界条件复杂、上部荷载类型变化以及梁下基桩承载力差异等情况进行分析计算。
