Space decomposition based parallelization solutions for the combinedfiniteediscrete element method in 2D

The combined finiteediscrete element method （FDEM） belongs to a family of methods of computationalmechanics of discontinua. The method is suitable for problems of discontinua, where particles aredeformable and can fracture or fragment. The applications of FDEM have spread over a number of disciplinesincluding rock mechanics, where problems like mining, mineral processing or rock blasting canbe solved by employing FDEM. In this work, a novel approach for the parallelization of two-dimensional（2D） FDEM aiming at clusters and desktop computers is developed. Dynamic domain decompositionbased parallelization solvers covering all aspects of FDEM have been developed. These have beenimplemented into the open source Y2D software package and have been tested on a PC cluster. Theoverall performance and scalability of the parallel code have been studied using numerical examples. Theresults obtained confirm the suitability of the parallel implementation for solving large scale problems.

Existing Conditions and Development of the Coastal Townships of Shanghai

Ⅰ.Existing Conditions and Char-acteristics of the Coastal Belt Townshipsof ShanghaiThe coastal belt of Shanghai is com-posed of 6 counties (i.e.the Baoshan,Chuansha,Nanhui,Fengxian,Jinshan andChongming) which have a total area of3,701 km~2(63% of the total suburban area)and have a total population of 3.54 million(63.8% of the total suburban population).Within these 6 counties,there are 5 county     

Application of artificial intelligence to rock mechanics: An overview

Different artificial intelligence(AI)methods have been applied to various aspects of rock mechanics,but the fact that none of these methods have been used as a standard implies that doubt as to their generality and validity still exists.For this,a literature review of application of AI to the field of rock mechanics is presented.Comprehensive studies of the researches published in the top journals relative to the fields of rock mechanics,computer applications in engineering,and the textbooks were conducted.The performances of the AI methods that have been used in rock mechanics applications were evaluated.The literature review shows that AI methods have successfully been used to solve various problems in the rock mechanics field and they performed better than the traditional empirical,mathematical or statistical methods.However,their practical applicability is still an issue of concern as many of the existing AI models require some level of expertise before they can be used,because they are not in the form of tractable mathematical equations.Thus some advanced AI methods are still yet to be explored.The limited availability of dataset for the AI simulations is also identified as a major problem.The solutions to the identified problems and the possible future research focus were proposed in the study subsequently.     

Performance of a Nonwoven Geotextile Reinforced Wall with Unsaturated Fine Backfill Soil

The use of marginal backfills in GSE （geosynthetic stabilized earth） walls has not been recommended by different standards specifications. Restrictions are motivated by the poor hydraulic conductivity of fine soils that are capable of developing of water pressures. However, the use of granular materials can expend the cost of the construction. As a result, local soils, granular or not, have been increasingly used. Unsaturated conditions of fine soils may result in convenient performance even using extensible reinforcements. This paper evaluates the performance of a full scale model of a nonwoven geotextile reinforced wall constructed with fine grained soil backfill. The unsaturated condition was maintained and matric suctions, displacements and reinforcement strains were monitored during the test. Results have shown that the unsaturated condition of the backfill allowed maximum reinforcement peak strain of 0.4 %. For the case of a wrap faced wall on a firm foundation the performance and good agreement between measured strains and factors of safety from limit equilibrium analyses have shown the maintenance of unsaturated conditions as an economical alternative to the use of high quality fill.     

A Probe into the Changing Pattern,Development and Distribution of Cities in China

Since the founding of the People's Re-public of China,the development of citiesand towns has been basically sound.Hun-dreds of cities have been either developed,renewed or emerged into modern cities.     

Multi-dimensional Evaluation of Recent Neighbourhood Renewal Projects in Beijing: Case Studies on Shichahai and Jinyuchi Neighbourhoods

Most of Chinese cities have experienced a great wave of large-scale neighbourhood renewal in recent years. However, only a few research works have been done in giving assessment after the completion of renewal projects. Aimed at such a circumstance, this paper, by referencing the experience of European countries, establishes a multi-dimensional evaluation framework to analyze the primary data drawn from recent household surveys of Shichahai and Jinyuchi neighbourhoods in Beijing, and puts forward some suggestions based on the conclusions drawn from the surveys.     

Change and Continuity:Chinese Villages in Transition (I)–Longmei Village

This is the first in a series of four articles ethnographically exploring instances of village transformation in peri-urban China.Each article presents an in-depth case study of a single village and its unique combination of change and continuity.Together,these case studies demonstrate the specificity and idiosyncrasy of village transformation and the need for planners to"take actions that suit local conditions"(yindi zhiyi).This first installment investigates Longmei Village in the Panyu District of Guangzhou Municipality.Longmei’s leaders have encouraged economic transformation through industrialization and real estate development while seeking to maintain the village’s socio-spatial continuity.These competing priorities have led to contradictions in Longmei’s development,as integration into economic networks brings new people,goods,and ideas to the village.This tension has intensified as both registered villagers and migrant workers have pursued divergent visions for Longmei’s future transformation.     

Norwegian oil and gas storage in rock caverns-Technology based on experience from hydropower development

Underground storage in rock caverns is widely used in Norway for many different petroleum products,such as crude oil,fuel,propane and butane.Basically,the caverns for such storages are unlined,i.e.containment is ensured without using any steel lining or membrane.The main basis for the storage technology originates from the extensive hydropower development in Norway.As part of this activity,about 4500 km of tunnels and shafts have been excavated,and around 200 large powerhouse caverns have been constructed.The hydropower tunnels are mainly unlined,with hydrostatic water pressure on unlined rock of up to 1000 m.Some of the projects also include air cushion chambers with volumes of up to 1×10⁵m³and air pressure up to 7.7 MPa.Many lessons which are valuable also for underground oil and gas storage have been learnt from these projects.For a storage project to become successful,systematic,well planned design and ground investigation procedures are crucial.The main steps of the design procedure are first to define the optimum location of the project,and then to optimize orientation,shape/geometry and dimensions of caverns and tunnels.As part of the procedure,ground investigations have to be carried out at several steps integrated with the progress of design.The investigation and design procedures,and the great significance of these for the project to become successful will be discussed.Case examples of oil and gas storage in unlined rock caverns are given,illustrating the relevancy of experience from high-pressure hydropower projects for planning and design of unlined caverns for oil and gas storage.
