Risk response is an important work in project risk management (PRM). To generate project risk response strategies, retrieving and reusing information and knowledge of the similar historical cases is important, while research concerning this issue is still relatively scarce. Taking the risk response of the subway project in S city, China as a case problem, this paper proposes a pragmatic method ...

Much of the research on data management for moving objects has assumed an outdoor setting in which objects move in Euclidean space (possibly constrained) or some form of spatial network and in which GPS or GPS-like positioning is assumed explicitly or implicitly. That body of research provides part of an enabling foundation for the growing Location-Based Services industry. However, we lead larg...

Aiming at the narrow and long tunnel structure, few internal features, a large amount of point cloud data, existing registration algorithms commercial software results are not ideal, an iterative global algorithm is proposed for massive underground registration, which composed local initial pose acquisition adjustment. Firstly, feature coordinates in extracted, then station-by-station performed...

Abstract Due to safety issues when passengers get on and off the subway spend a lot of time subway, this makes station signs very important. Moreover, in case fire other dangerous situations emergency evacuation, guiding must be able guide leave areas efficiently orderly, so as protect personal property passengers. The purpose study was analyze decision response evacuation using characteristics...

A subway station is a confined space, so it very important to evacuate people safely in case of fire. It necessary study and analyze the smoke distribution evacuation ability different layout schemes when fire occurs. Taking as an example, this paper combines BIM (Building Information Model) technology with safety station. First, we optimize public area use establish model. Then, PyroSim softwa...

To investigate the effect of deep foundation pit excavation on stability retaining structure, a subway station in city Jinan was selected as project, and FLAC3D-based three dimensional model developed for numerical simulation. The horizontal displacement axial force support, vertical column were studied compared to collected data from field. findings indicate that when is excavated, maximum def...
