The 2011 International Conference on Materials Engineering for Advanced Technologies(ICMEAT 2011)

作者： Su Qiaomei Wang Jianmin Guo Jiaojiao Department of Surveying Science and Technology Taiyuan University of Technology

earthwork is an important content in engineering constructionThis paper explores a scientific method of earthwork calculation, designs and develops corresponding software which accurately calculates the earthwork, effectively reduces engineering investment and budget deviationIt mainly studies the three-dimensional model building by the complex form through two period observationsThe model building methodology mainly adopts the elevation of two period observation data`s mutual insertion to establish the two period superposition triangle netAnd then getting the method of calculating tri-prism volume formed by triangularThis method, the volume calculation principle is simple, high precision, and the design of the special software system is based on the above methodAt present, the software system applies in the engineering, and it has computational fast, convenient, results accuracy and reliable etc., advantages.

Current research on Digital Twin(DT)is largely focused on the performance of built assets in their operational phases as well as on urban ***,Digital Twin has not been given enough attention to construction phases,for which this paper proposes a Digital Twin framework for the construction phase,develops a DT prototype and tests it for the use case of measuring the productivity and monitoring of earthwork *** DT framework and its prototype are underpinned by the principles of versatility,scalability,usability and automation to enable the DT to fulfil the requirements of large-sized earthwork projects and the dynamic nature of their *** computing and dashboard visualisation were deployed to enable automated and repeatable data pipelines and data analytics at scale and to provide insights in near-real *** testing of the DT prototype in a motorway project in the Northeast of England successfully demonstrated its ability to produce key insights by using the following approaches:(i)To predict equipment utilisation ratios and productivities;(ii)To detect the percentage of time spent on different tasks(i.e.,loading,hauling,dumping,returning or idling),the distance travelled by equipment over time and the speed distribution;and(iii)To visualise certain earthwork operations.

Simulation of earthworks Based on EON,3DS Max and AutoCAD

引用

International Journal of Plant Engineering and Management 2014年第2期19卷 72-77页

作者： LAI Bing-heng LI Chang-hua HOU Xiao-ting School of Information and Control Engineering Xi'an University of Architecture and Technology College of Science Xi'an University of Architecture and Technology

In view of the earthwork construction tions, and earthworks cannot be verified, using with long duration, heavy and complicated construction condivirtual reality technology to simulate the process of its construction. As a hydropower project for an example, the terrain model using AutoCAD and 3DS Max combination of building, equipment model in 3DS max using entity model building. In the transporting section, will be built in 3DS max key frame together with the model of import in the EON and set the parameters of the animation node; In digging scene, using multiple place nodes to control of the excavator digging operation ; Interaction part of the scene, using the built-in mouse node （Click Sensor） and keyboard nodes （Keyboard Sensor） implementation scenarios and user interaction. Research shows that through excellent virtual reality software EON to apply virtual reality technology in earthwork construction simulation stage, found possible quality problems and potential safety problems in engineering, through the simulation can be more perfect earthwork construction. Verified, earthwork construction of virtual real earthworks has certain guidance and reference value.

Proposing a“lean and green”framework for equipment cost analysis in construction

引用

Frontiers of Engineering Management 2019年第3期6卷 384-394页

作者： Ming LU Nicolas DIAZ Monjurul HASAN Department of Civil and Environmental Engineering University of AlbertaEdmontonAlberta T6G 1H9Canada

One limitation of previous productivity-driven research on equipment selection and operation simulation lies in the fact that the green aspects of construction activities have been largely neglected in analysis of costefficiency of construction *** the other hand,studies attempting to measure greenhouse gas emission due to construction activities have yet to develop a methodology that correlates their findings and implications with construction *** order to address the immediate need for improving the sustainability performance of construction projects,it is imperative for the construction industry to evaluate greenhouse gas emission as a cost factor in construction planning,equipment selection,and cost *** this context,this paper formalizes an integrative framework for equipment cost analysis based on the concepts of lean construction and green construction,aimed to guide the selection of appropriate construction equipment considering exhaust emission and productivity performance at the same *** framework is elaborated in earthwork construction in order to evaluate the impact of greenhouse gas emission in estimating equipment hourly rates and assessing greenness and sustainability for alternative equipment options.
