The loss of the diesel soot and smoke Cha Cha PAHs in the leaching rate of the most important factor is the length of brewing time;PAHs were detected in the loop on the small number of PAHs,5 of the ring PAHs were only in the low level of test,and the experiment detected no PAHs, detected no 6 of the ring,regardless of diesel smoke or soot Cha Cha,the concentration of PAHs has the highest concentration of dihydrogen Acenaphthene;On the influence of the number of brewing tea,the total concentration and the leaching rate of PAHs in the soot and smoke Chai tea are lower than on the influence of the brewing time and temperature.
其中影响煤烟茶和柴烟茶中PAHs浸出率的最主要因素都是冲泡时间的长短;检测出的PAHs都集中在环数较少的PAH,5环的PAHs仅在较少的试验水平中检出,无6环的PAHs检出,无论煤烟还是柴烟茶中PAHs的浓度都以二氢苊的最高;在冲泡次数影响下,煤烟茶、柴烟茶中PAHs的总浓度和总浸出率,比在冲泡时间和温度影响下要低。

In order to understand the seismic performance of the large complex structure with basement, the structure-pile-soil finite element model of two typical cross sections of the Tianjin Transportation Junction were established by using the ANSYS software. The elasto-plastic time history analysis was made, and the seismic responses of the whole system under the horizontal seismic load were got. Comparing the results of the seismic response with the rigid foundation model, some reasonable conclusions are drawn.
为弄清楚带有地下室大型复杂结构的抗震性能,本文针对天津站交通枢纽工程,分别取结构典型的横向及纵向剖面,应用大型通用有限元分析软件ANSYS,建立了结构-桩-土体系相互作用的有限元模型,采用动力时程分析方法,研究体系在水平地震作用下的弹塑性动力反应规律,分析结构在地震动作用下的位移和内力的分布;并与假定刚性基础周边土简化为弹簧的结构模型的计算结果进行比较,通过两种模型的地震反应的对比分析,得到了一些有益的结论。
