摘要：针对输电线路中山区上覆土层、下卧岩层的地层条件,为增加桩基础抗拉拔性能,提出了一种锚固板钢筋锚固形式的斜锚短桩基础,开展了钢筋混凝土短桩-3向斜锚杆基础节点室内模型试验,研究了拉拔荷载作用下桩锚节点的受力特性与破坏机制。结果表明:短桩与锚筋协同工作,最先于锚杆节点处产生拉裂缝,进而形成竖向主裂缝不断向桩顶延伸,致使试件整体劈裂破坏。试件的开裂荷载约为150 kN、屈服荷载约为1611 kN、极限荷载约为1845 kN,破坏前锚筋全部屈服,桩内纵筋、箍筋均未屈服,斜锚表现出稳定的锚固性能。斜锚短桩基础受力较小时,桩锚间的锚固作用主要由钢筋直锚段的黏结作用承担;随着荷载逐渐增加,锚固作用则主要由锚固板端头的承压作用承担,锚杆肋间斜向应力与短桩相应位置斜截面切应力τ_α叠加,使得锚筋周围混凝土裂缝发生偏转,加剧混凝土裂缝向桩表面发展。研究成果可为复合型基础的设计提供借鉴,并为其变形特性与破坏机制研究提供参考。

摘要：以棉花秸秆为原料、ZnCl_(2)/AlCl_(3)为改性剂制备活性炭(AC)。利用中心复合设计法(CCD)对主要影响因子进行参数优化,并利用预测模型确定最佳制备工艺为:活化温度为640℃、浸渍质量比(棉秸秆与改性剂的质量比)为1.58∶1、活化时间为87 min、改性剂配比(改性剂中ZnCl_(2)与AlCl_(3)的质量比)为9∶1。在实际实验条件下,样品得率、总酸含量分别为44.32%、0.87mmol/g,与模型预测值误差分别为1.79%、1.04%。利用碱性有机染料甲基紫研究其吸附性能,当活性炭投加量为1.18 g/L、溶液质量浓度为82.00 mg/L时,其对甲基紫去除率均能达到90%以上。ZnCl_(2)/AlCl_(3)改性棉秸秆基活性炭具有良好的吸附性能,为棉秸秆的应用提供了参考依据。

摘要：Mountain tunnel crossing a normal fault in seismically active zone is easily affected by normal fault slip and earthquake. It is necessary to study tunnel dynamic response under action of normal fault slip and earthquake. In this paper, a three-dimensional normal fault sliding device was designed, and a shaking table test was carried out to study tunnel seismic performance under normal fault slip. The results show that peak acceleration of lining is dominated by an existence of fault and direction of seismic excitation, not normal fault slip. And the incremental strains of lining in critical zone with 1.7 times fault thickness and centered in faults induced by normal fault slip and seismic excitation are larger than ones only by seismic excitation. And the incremental strains in critical zone increase with the increase of normal fault slip magnitude ranging from 0 to 2 mm. And normal fault slip results in a significant reduction of overall tunnel stiffness subjected to an earthquake. These experimental results provide a scientific reference for prevention and control measurement of tunnel damage under earthquake and normal fault slip.

摘要：本文构建了广告投放与消费者电话反应之间的几何滞后分布的动态计量经济模型,并利用实测数据对不同报刊媒体的短期广告效果进行了评价。研究结果显示,所建立的模型可以较好地对同一类广告媒体进行评价和预测;消费者电话反应具有广告的短期刺激-反应特征,以报刊的发行量作为报刊选择的标准可能导致偏差;报刊广告的保留率很低,以报刊广告为主的企业可以考虑每天或隔天作为广告投放的频率。
