文章建立了三角门船闸物理模型,通过物理模型试验研究了开通闸运行时闸室、引航道的水动力条件以及闸门启闭机的受力。在此基础上,提出了开通闸运行的判别方法,确定了该船闸宜进行开通闸运行的临界上下游水位差。研究结果表明,不同来流条件下,当上下游水位差处于-0.35~0.37 m,且不超过设计水位时,闸室和引航道主流波动较小,流速对开通闸运行影响不大,且船闸启闭机受力不超过设计值,焦港船闸可进行开通闸运用。

为了提出一种新的量化人员疏散瓶颈的识别方法。以某地铁站为例,运用EVACNET4模型软件,模拟该地铁站发生火灾等事故时,人群的疏散情况,采用网络结构效益与结构重要度结合的方法查找疏散过程中的瓶颈所在,通过计算疏散瓶颈的结构重要度,将各瓶颈按其对车站安全疏散的影响程度排序,找出瓶颈制约点。结果表明:地铁站内的自动扶梯的开闭状态对疏散时间的影响很大,在发生火灾等特殊事件时应将自动扶梯停止运行,当作楼梯使用。同时,闸机的开闭状态也会影响疏散时间,但只要保障疏散过程中闸机可用,人员均能在规定的时间内完成疏散。通过对比分析门扉式闸机和三杆门式闸机的优劣,在建设地铁时,主要应以门扉式闸机为检票通道。
The purpose of this study is propose a new method of bottleneck identification in the evacuation process. The modeling software EVACNET4 was applied to simulate the evacuation of crowd in a certain subway station when fires and other accidents happened.A combination method of network structure effectiveness and structural impor-tance was applied to find the bottlenecks in the evacuation process.By calculating the structural importance of e-vacuation bottlenecks, the bottlenecks were sorted by their impact on the safe evacuation of the station, so as to find out the bottleneck restriction points.The results showed that the opening and closing state of the escalator in the subway station has a significant impact on the evacuation time.When special events occurs, such as a fire, the es-calator should be stopped and used as stairs.Meanwhile, the opening and closing state of the gates also affect the evacuation time, but as long as the gates is available in the evacuation process,

In water conservancy hub projects located at plains,usually the pumping station and sluice are integrated together for a compact layout to save land and reduce costing.However,this combined layout can result in unwanted flow patterns,such as locally reverse flow,strong lateral current and so on.Thus,as a case study,the asymmetrical layout of integrated pumping station and sluice in North Yaoguang Water Conservancy Hub Project is optimized and finalized based on two-dimensional numeri-cal stream simulations and a detailed discussion about the layout rationality and safety of navigation.It is shown that it is proper to install a diversion pier between the pumping station and the sluice upstream and downstream in order to alleviate uneven flow patterns and satisfy the safety of navigation.Additio-nally,the diversion pier can drive the reverse flow zones to further upstream and an increased length of the piers can reduce the velocity of lateral current.A trash rack bridge is inst
