Resilience assessment and optimization method of city road network in the post-earthquake emergency period

The post-earthquake emergency period,which is a sensitive time segment just after an event,mainly focuses on saving life and restoring social order.To improve the seismic resilience of city road networks,a resilience evaluation method used in the post-earthquake emergency period is proposed.The road seismic damage index of a city road network can consider the influence of roads,bridges and buildings along the roads,etc.on road capacity after an earthquake.A function index for a city road network is developed,which reflects the connectivity,redundancy,traffic demand and traffic function of the network.An optimization model for improving the road repair order in the post-earthquake emergency period is also developed according to the resilience evaluation,to enable decision support for city emergency management and achieve the best seismic resilience of the city road network.The optimization model is applied to a city road network and the results illustrate the feasibility of the resilience evaluation and optimization method for a city road network in the post-earthquake emergency period.

Research on the Model of General Landscape Planning of City Road System

This paper analyses the overall landscape framework of city road system in ancient and modern China, using the ideal state terrain model which was fi rst recorded by the construction system of the Zhou Dynasty, and summarizes the ideal model of overall landscape framework of city road system, based on Chinese psychological needs of landscape, and conducts the applied research taking Nanchong in Sichuan, China for example.

Marie's Suffering in A Road to the Big City from the Perspective of Feminism

Some scholars concerns about the conflicts between Marie and Lilla, but few of them studies the conflicts between femaleand male in the novel. In the novel, Marie's suffering is not only from the fraudulence of her sister, but also from the oppression ofmale by the perspective of feminism.In the family, it implies that she is oppressed by male, which can be understood from the differ-ence of their jobs and the traditional image of her mother, while in the society, she suffers a lot from Jansen, which can be seen fromthe descriptive perspective of appearance of Marie, the dialogue between waitress and Jansen, the dialogue between Marie and Jan-sen as well as Jansen's decision to the leaving of Marie. The double oppression of Marie's suffering both reflects the unequal posi-tion of male and female.By this analysis, it can impulse female to improve themselves and it also calls on female to get along wellwith male by the appropriate way.

Research on the Optimization Design of Intersections for Safe Operation of Large Trucks

When big trucks are running at urban road intersections,they are easy to interfere with other motor vehicles,and the turning big trucks are easy to have conflicts with non-motor vehicles and pedestrians,which will affect the safety of intersections.This paper first studied the intersection of trucks to the running trajectory,on this basis,through the establishment of mathematical model analysis of large truck steering conditions inside the wheel,and the influence of blind area to the driver.In the research of intersection safety design,the safety design is divided into three parts:Entrance road,internal operation and signal control.At the same time,the design method of the entrance road,the interior of the intersection and the signal control is given,which improves the safety of the truck driving at the intersection.Finally,the intersection of Jungong road and Zhoujiazui road in Yangpu district of Shanghai was selected as a case,and the optimal design of the intersection for large trucks was carried out through the investigation and analysis of actual data.The evaluation and analysis were carried out by using the multi-index matter-element model.The results show that the comprehensive safety correlation degree of the intersection is reduced to 0.42,and the safety level of is improved by one level.

Impacts of opening baffle of city road tunnels on natural ventilation performance

Based on the opening baffle mode for natural ventilation of city road tunnels,this paper studies the impacts of opening baffle on natural ventilation performance by verifying numerical simulation through model tests.By analyzing the impacts of installation angle,dimension,location,and quantity of opening baffle on ventilation performance,the paper reached the conclusions as follows:1)When installation angle is larger than 45°and tunnel ventilation is well operated,the baffle exhaust could increase by at least 30%compared to when there is no baffle.2)The baffle reaches its optimal performance when the length of the baffle is equal to the width of the city road tunnels.3)Baffle exhaust could increase by 30%when it is installed in the downstream of openings.4)The performance of a single baffle is better than that of multiple baffles.
