Based on the Yishan Metro Station Project of Shanghai Metro Line number 9, a centrifugal model test was conducted to investigate the behavior of stratified settlement and rebound (SSR) of Shanghai soft clay caused by dewatering in deep subway station pit. The soil model was composed of three layers, and the dewatering process was simulated by self-invention of decompressing devise. The results ...

Taking a double-line underground excavation subway tunnel underneath the medium-low-speed Maglev bridge section of Beijing S1 Metro line as project reference, deformation control index metro and track panel was studied using numerical simulation data monitoring, under conditions deep-hole grouting measures for soil layer around active lifting superstructure viaduct. The results show that maximu...

This paper reports on proposed solutions to the recovery from faults in a generic class of networks, where customer access is achieved via long-reach passive optical networks (LR-PONs), with the majority of customers enjoying protection in the backhaul regime to two separate metro nodes. Initial modelling studies suggest that in the event of a cable failure or single equipment element failure, ...

Edge bundling reduces the visual clutter in a drawing of a graph by uniting the edges into bundles. We propose a method of edge bundling drawing each edge of a bundle separately as in metro-maps and call our method ordered bundles. To produce aesthetically looking edge routes it minimizes a cost function on the edges. The cost function depends on the ink, required to draw the edges, the edge le...

Abstract. We initiate a new problem of automatic metro map layout. In general, a metro map consists of a set of lines which have intersections or overlaps. We define a set of aesthetic criteria for good metro map layouts and present a method to produce such layouts automatically. Our method uses a variation of the spring algorithm with a suitable preprocessing step. The experimental results wit...

Metros are the principal means of public transportation in many of the world’s cities, and continue to grow in the face of rising demand. Expanding metro infrastructure is costly, however, and at a certain point becomes unsustainable. When this occurs the only feasible solution is to improve the train’s management system by using either offline approaches, such as pre-programming schedules whic...
