生态带共建视域下京津冀地区减污降碳协同效应研究

京津冀地区碳污(大气中碳排放和污染物排放)排放量与环境承载力极不匹配,区域环境协同治理虽可以从排放端缓解碳污超排压力,但减排潜能不足仍需引入“自然适应”方式提升环境治理效率。基于此,该研究在测度碳污排放量基础上,使用Copula模型对京津冀地区碳污协同风险进行识别,并结合区域生态带类型及其碳污吸收特征,对碳污排放和吸收匹配关系进行动态分析;同时以京津冀地区共建度为主要影响因素,逐渐增加京津冀地区生态带规模,分别设置基准、保守、折中、激进共4类10个情景进行模拟,分析不同共建水平下绿色生态带与净碳污排放量间的互动博弈关系。结果表明:①2011-2019年,京津冀地区大气中碳排放量波动上升并在2018年达到最大值(1323.164 Mt),污染物排放量波动下降并在2015年达到最大值(402.9×10^(4) t)。尽管京津冀地区污染物排放风险有所降低,但碳排放风险并未随之降低。②京津冀地区13个城市碳污排放量大于生态带碳污吸收量,其中保定市、张家口市、承德市符合减污降碳发展方向,唐山市、天津市、石家庄市、邯郸市、北京市与减污降碳方向相反,秦皇岛市、沧州市、廊坊市、衡水市、邢台市属于“低排低吸”类型。③各情景模拟中,激进情景下碳污排放综合风险值最小,为0.055;S0情景下碳污排放综合风险值最大,为0.648,情景模拟发现绿色生态带共建可以有效提高减污降碳效能,从而降低京津冀地区净排放量,且共建水平越高越符合减污降碳发展目标。研究显示,京津冀地区13个城市碳污平衡匹配关系不稳定,虽然京津冀地区生态带共建可以在一定程度上缓解碳污超排问题,但加大协同治理力度仍是减污降碳的重要途径。

装配式叠合楼板后浇带接缝处细节施工研究

叠合楼板因整体性能好、构造简单、弹性好以及使用便捷等优势在装配式建筑中具有广泛的应用价值,装配式叠合楼板后浇带接缝处因模板与后浇带叠合板存在空隙等导致其存在漏浆通病问题,其不仅影响装配式建筑的整体美观,而且还增加施工成本。鉴于此,以某装配式项目为例,针对传统施工模式下后浇带接缝处存在的漏浆通病,提出在模板底部采取螺杆反吊和利用废钢筋焊接形成自拉加固体系,加固接缝处模板,以此减少叠合板后浇带接缝空隙,控制叠合板后浇带接缝漏浆通病。

寒区某超长隔震结构建造全过程温缩变形分析

针对严寒地区某超长隔震结构建造周期长、平面形状复杂、结构跨度大、季节温差显著及分阶段施工的特点,建立了超长隔震结构建造全过程隔震层温缩变形的计算方法,结合现场的施工进度、方案和步序,采用有限元软件对建造全过程进行了详细的模拟,分析了结构建造全过程隔震层的温缩变形大小及演化规律,并与现场实测结果进行对比验证,最后探讨了结构分阶段施工、施工路径及后浇带设置方式对隔震层温缩变形的影响规律.结果表明:建造全过程温缩变形的模拟结果与实测结果吻合较好,隔震层的温缩变形随着施工进度推移大体呈周期性变化,且与环境温度变化有很大的相关性;超长隔震结构分阶段施工时,各阶段结构之间存在相互约束作用,结构最终的温缩变形是各阶段结构协调变形的结果;合理的施工路径和结构单元划分,能有效减小隔震层的温缩变形;相较于不设置后浇带的情形,当结构后浇带处附加钢筋连通时,隔震层最大温缩变形仅降低了6.3%,而当后浇带处钢筋全部搭接时,隔震层最大温缩变形降低36.3%.
