The project of Hangzhou Metro Line 1 is the first metro line of the urban rapid rail transit system in Hangzhou, China, which is one of the largest municipal projects of Hangzhou and is being constructed commencing fromMarch 28, 2007 and expected to be completed by October 1, 2012. This metro line has a total length of 48 km and 34 stations, connecting Hangzhou downtown with the suburban area o...

The optimization design of the section morphology of large-span tunnels plays an important role for saving cost and improving the engineering stability. The flat ratio of tunnel which is as an important control index, its rationality is the key problem in the design of tunnels. Program with Python to set up the dynamic calculation model of a large-span tunnel planned to be constructed which can...

Under increased urban settlement density, access to a high resolution (land-parcel scale) bare-earth Digital Elevation Model (DEM) is a pre-requisite for much decision support for planning: stormwater assessment, flood control, 3D visualisation, automatic delineation of flow paths, sub watersheds and flow networks for hydrological modelling. In these terms, a range of options face the DEM-build...

The effects of culture conditions and chloramphenicol treatment on the induction of the marine bacterium Pseudoalteromonas spongiae to larval settlement of Hydroides elegans were investigated. The results showed that P. spongiae cells grown in the medium containing both yeast extract and peptone (YP-grown P. spongiae) was highly inductive to larval settlement, whereas P. spongiae cells grown in...

Impact pile driving is a multi-component problem which is associated to multi-directional ground vibrations. At first, vibration is transferred from the hammer to the pile and then to the common interface of pile and soil. This is then transferred to the environment and has great impact on the adjacent structures, causing disturbance to residents and also damage to the buildings. It is of high ...

he U.S. dollar clearing and settlement system was little noticed during the recent financial crisis, mainly because it performed dependably, processing record volumes and values of trades made in stressed financial markets. Its successful operation was in part a result of the collaborative efforts undertaken by stakeholders over decades to improve risk management and operational resiliency. Und...

Based on the data of Jiangzhai one-stage settlement sites archaeological excavation data, this paper applies three-dimensional visualization technology of virtual reality to scenario building. In order to enhance the fidelity of prehistoric settlement sites to reproduce the virtual system simulation results in the system design and implementation process, it essential to build plenty of the nat...

Abstract The waste tyre-derived products, including whole tyres, tyre bales, shreds, chips, and crumb rubber, have begun to be used in various geotechnical applications. In particular, the use of bales construction a lightweight embankment on soft ground has potential satisfy demand for low-cost materials exhibiting such beneficial properties. This paper presents comparison between common mediu...
