The explosive increase of construction and demolition waste(CDW) caused the insufficient source separation and emergency disposal at domestic waste landfills in many developing countries. Some organic fractions were introduced to the CDW landfill process and resulted in serious odor pollution. To comprehensively explore the impacts of organic matters on odor emission patterns, five CDW landfills(OIL), with organic matters/inert CDW components(O/I) from 5% to 30%, and the control group only with inert components(IL) or organics(OL) were simulated at the laboratory. The chemical and olfactive characters of odors were evaluated using the emission rate of 94 odorants content(ER_(total)), theory odor concentration(TOC_(total)), and e-nose concentration(ER_(ENC)), and their correlations with waste properties were also analyzed. It was found that the main contributors to ER_(total)(IL: 93.0% NH_(3);OIL: 41.6% sulfides, 31.0% NH_(3), 25.9% oxygenated compounds) and TOC_(total)(IL: 64.1% CH_3SH, 28.2% NH_(3);OIL: 71.7% CH_(3)SH, 24.8% H_(2)S) changed significantly. With the rise of O/I, ER_(total), TOC_(total), and ER_(ENC) increased by 10.9, 20.6, and 2.1 times, respectively. And the organics content in CDW should be less than 10%(i.e., DOC < 101.3 mg/L). The good regressions between waste properties(DOC, DN, pH) and ER_(total),( r = 0.86, 0.86,-0.88, p < 0.05), TOC_(total),( r = 0.82, 0.79, -0.82, p < 0.05) implied that the carbon sources and acidic substances relating to organics degradation might result in that increase. Besides, the correlation analysis results( ER_(ENC) vs. TOC_(total,, r = 0.96, p < 0.01;vs. ER_(ENC), r = 0.86, p < 0.05) indicated that e-nose perhaps was a reliable odor continuous monitoring tool for CDW landfills.

提出了基于概率密度演化方法的正交异性钢桥面板焊接节点时变疲劳可靠度评估方法,并以润扬大桥顶板-U肋焊接节点为对象开展应用研究。首先,基于S-N曲线和Miner准则,构建了可同时考虑疲劳性能退化和荷载效应增长的钢桥面板焊接节点疲劳极限状态函数,并导出其概率密度演化方程。然后,采用有限差分法求解该方程,据此得到概率密度演化曲面,进而建立其时变疲劳可靠度评估方法。最后,通过工程实例验证了所提方法的可行性和准确性,并探讨了疲劳性能退化和荷载效应增长对该节点时变疲劳可靠度的影响规律。研究表明:与Monte Carlo法相比,该方法不仅精确高效,还能捕捉概率密度演化信息;疲劳性能退化和荷载效应增长会显著影响钢桥面板焊接节点的疲劳寿命。
