Fabrication of the box beam is divided into such parts as reinforcement, formwork, concreting, prestressing, moving and storing of beam, pipe grouting under pressure, end sealing of the beam, water - proof layer on the bridge surface system, protective coating etc. the paper makes description of effective box beam construction technology and workmanship which can be adopted in other projects, such technologies as : manufacturing and fixing of reinforcement, steel reinforcement fixing baseplate, web plate and top plate respectively and lifting the steel skeleton into form, requirements of design and manufacturing and way of utilization for dismantling - erection type formwork and hydraulic formwork, optimization of concrete ratio, concrete pouring process of two ends of beam in priority over the middle, in sequence of first baseplate followed by web plate and top plate at last, concrete pouring in inclined section and in horizontal layer, concrete vibration mainly by external vibrator in assistance with internal vibrator, methods and regulation for steam curing of concrete, dual controls over stress and strain to ensure quality of prestressing workmanship, construction method of effective beam moving by heavy - weight special moving facility, some regulations and key notes about construction of grouting under pressure, beam ends sealing, water - proof layer on the bridge surface system, protective coating
箱梁製造由鋼筋工程、模板工程、混凝土工程、預應力工程、移存梁工程、孔道壓漿工程、梁體封端工程、橋面防水層和保護層工程等施工環節組成。文中介紹的採用胎具製作和綁扎鋼筋,分底腹板和頂板分別綁扎並吊裝鋼筋骨架入模;拆裝式和液壓式兩種模板的設計、製作要求和使用方法;綜合考慮、優化混凝土配合比,混凝土灌注從兩端至中間、先底板、后腹板、再頂板的施工順序和斜向分段、腹板水平分層、附著式振搗為主、插入式搗固為輔的施工工藝,蒸汽養護的方法和規定;應力應變雙控制確保預應力施工質量的施工技術;採用重物移運器有效移梁的施工方法;壓漿、封端、橋面防水層和保護層施工的一些規定和注意事項等都是對箱梁製造行之有效的施工技術和施工方法,並可為以後類似施工作借鑒。3. based on the bond test for 33 concrete specimens and gfrp and bending test for 15 beams strengthening with gfrp, surface preparation of concrete, type of epoxy adhesives, thickness of adhesives, hardening time of adhesives, cure condition after strengthening are considered, and the effect on concrete structures strengthening with gfrp causing by construction behavior was analyzed. 4
根據gfrp片材加固混凝土結構在施工中常涉及到的一些相關因素,如混凝土基層表面處理情況、所選用的粘結劑類型、塗抹粘結劑的厚度、加固的方式以及養護狀況,進行了33個混凝土試件與gfrp片材的剪切粘結試驗,並進行了採用gfrp片材加固的15根混凝土梁的抗彎試驗,分析了與施工性能相關的因素對gfrp片材加固混凝土結構效果的影響。The paper use drucker - prager model as the constitutive model of soil, use pole module as the model of soil nails, use girder module as the model of soil - cement mixing piles, use goodman module as the model of interface, an iterative - increment method is used to solve nonlinear equation. 2. the paper has a further research on the influence of compound soil nailing behavior in the perspective and the axial strength of the soil nails of the effect of the stiffness of soil, the stiffness of soil - cement mixing piles, the width of soil - cement mixing piles, the length of nails, the angle of nails
本文根據目前復合型土釘墻支護的研究現狀和工程實際需要,採用有限單元法對攪拌樁-土釘復合型土釘墻的力學特性進行數值分析,本文的主要工作內容有以下幾個部分: 1 .利用同濟曙光有限元軟體( geofba )對攪拌樁-土釘復合型土釘墻支護進行了非線性有限元分析,在有限元計算中,本文採用了drucker - prager模型作為土體的本構模型,土釘採用了桿單元模型,攪拌樁和噴射混凝土面層的組合體採用了梁單元模型,接觸面單元採用了goodman單元模型,非線性求解方法為增量迭代法。In our country, most of bridges were built in 1960s or 1970s, which were based on that time traffic discharge and development planning, so design criterion of these bridges were very lower. in addition, it was inevitable to bring about cracks > concrete rupture, steel rust ^ honeycomb and water proof layer failure, because some established bridges were built by poor construction and maintenance during the course of operating period. all above mentioned lead to durability and bearing capacity could n ' t gain to design standard
由於我國很多橋梁建於上個世紀六、七十年代,基於當時的車流量和各方面的發展規劃,橋梁設計等級普遍偏低;另外,某些既有橋梁由於施工質量差和運營期間維護不到位,不可避免地會產生裂縫、混凝土破損、鋼筋銹蝕、蜂窩及防水層失效等缺陷,從而導致耐久性及承載力達不到設計要求。分享友人
