    摘 ?要:為提升山區丘陵等施工環境復雜地段的輸電鐵塔基礎建設效率,以廣泛應用的板式基礎為研究對象,基于模塊化、標準化及規范化的設計思想,分析了其受載特性及傳荷路徑,研發了裝配式板式基礎模塊化方案和節點連接設計方法,并通過具體工程實例對設計方法進行了理論研究,最后利用ABAQUS軟件對設計實例中的基礎整體及節點受力情況進行了仿真分析。結果表明:裝配式板式基礎各模塊受力合理,荷載傳遞路徑明確,鋼筋及節點連接構件應力與理論計算結果接近,能滿足工程設計要求。 Abstract: In order to improve the efficiency of transmission tower foundation construction in mountainous and hilly areas with complex construction environment, the plate foundation widely used in transmission lines was taken as the research object. Based on the design idea of modularization, standardization and normalization, the loading characteristics and load transfer path of the foundation were analyzed. In order to meet the structural stability and component strength, the modular scheme of assembled slab foundation and the design method of joint connecting component were systematically studied, and the theoretical application of the design method was carried out through specific engineering examples. Finally, ABAQUS software was used to analyze the stress of whole foundation and joints in the design example. The results show that the stress of steel bar and joint connection members are close to the theoretical calculation results, and meet the engineering design requirements, which proves the feasibility of the design method.

    摘 ? 要:為了解石粉含量對機制砂混凝土的性能影響,制備了2%、5%、7%、10%四種石粉含量的機制砂混凝土,分別研究了其力學性能、工作性及耐久性,探究了不同石粉含量機制砂在預制構件混凝土中的應用,進行了裝配式構件的試生產。結果表明:在合適摻量下,石粉在一定程度上能改善機制砂的堆積密度,從而提高混凝土強度;石粉含量過大會降低混凝土密實性,從而影響混凝土力學性能;采用機制砂配制的混凝土力學性能、抗滲性能和抗凍性能可以達到與天然砂混凝土的同等水平。 Abstract: In order to study the influence of stone powder content on the performance of manufactured sand concrete, the manufactured sand concrete with 2%, 5%, 7% and 10% of stone powder was prepared, and its mechanical properties, working performance and durability were studied respectively. The application of manufactured sand with different stone powder content in prefabricated component concrete was studied, and the prefabricated component was producted in factory. The results show that stone powder can improve the strength of the concrete by improving the bulk density of manufactured sand in a certain extent. Excessive stone powder content will reduce the compactness of concrete and have bad effect on the mechanical properties of concrete. The mechanical properties, impermeability and frost resistance of concrete with manufactured sand are similar to those of concrete with natural sand.
