Analysis for the internal force of pile capping beam considering continuity of soil mass 考慮土體連續(xù)性的樁基承臺(tái)梁內(nèi)力分析
The design and construction of obliquely supported high bent for pier cap beams of lu pu bridge 上海盧浦大橋墩柱蓋梁斜撐高排架的設(shè)計(jì)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 條形樁基承臺(tái)梁在我國(guó)現(xiàn)代建筑工程中應(yīng)用極為普遍,其設(shè)計(jì)計(jì)算大多采用倒置的連續(xù)梁模式進(jìn)行簡(jiǎn)化計(jì)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 摘要在詳細(xì)調(diào)查的基礎(chǔ)上,介紹了107國(guó)道槐河大橋橋臺(tái)蓋梁裂縫的分布情況,深入分析了裂縫形成原因,并闡述了該橋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 本文結(jié)合湖南省自然科學(xué)基金項(xiàng)目“樁基承臺(tái)梁優(yōu)化設(shè)計(jì)理論與方法研究” ,針對(duì)非文克爾地基(半空間、線性變形層或單向壓縮層地基模型等)上的樁基承臺(tái)梁,提出一種利用地基柔度矩陣來進(jìn)行迭代的有限單元法,可充分考慮梁下土體的連續(xù)性,并對(duì)基礎(chǔ)與土體脫開、承臺(tái)梁截面變化、梁體邊界條件復(fù)雜、上部荷載類型變化以及梁下基樁承載力差異等情況進(jìn)行分析計(jì)算。
