Symmetries of the Beijing Heping Temple Complex

Three-dimensional laser scanning technology has been more mature, and its application fields are expanding. It is being used in key projects and important work such as ancient building recording, restoration and reconstruction. In this paper, the technology is applied to the 3D scanning, data splicing and model simplification of Heping temple building complex in Beijing. After innovative research on ancient architecture, it is found that the group layout, single form and local components of Heping temple building complex in Beijing show symmetry everywhere, vividly reflecting the extensive and profound ancient architectural culture and order. This points out a new direction for the development and application of 3D laser scanning technology and opens up a new path for the in-depth study of the protection of ancient buildings in China.

Influencing Factors of Disturbance Effects of Blasting and Driving of Deep Mine Roadway Groups

The development and application of roadway group layout methods in coal mines have become more common and the mutual disturbance of blasting and driving of roadway groups has also become more prominent at depth. To improve the stability of rock mass surrounding roadways, we performed a systematic study on the factors that influence blasting and driving disturbances of adjacent roadways in deep mine roadway groups. We use the dynamic analysis module in FLAC3D to obtain the influence laws of three factors on the disturbance effects of adjacent roadways, namely, excavation methods, layer position changes of the roadway group, and whether or not bolt support is applied in the first roadway. Blasting strongly influences the surrounding roadway and increased horizontal distance can effectively reduce the disturbance effects of blasting and driving between adjacent roadways compared with increased vertical distance. Bolt support of the first excavated roadway enhances the roadway integrity and better stabilizes the rock structure surrounding the roadway. Industrial tests were carried out on three uphill roadways in the Gubei no. 1 mine (6-2). The monitoring results show that the movement of the roof and floor of the floor uphill return wind roadway is larger than that on the two sides. There is no notable change in the deformation speed of the surrounding rock in the floor return air roadway, but the deformation speed of the uphill conveyor belt roadway changes significantly. The results show that when the blasting excavation of a deep mine roadway group is more than five times the tunnel spacing, the increased horizontal distance effectively reduces the disturbance effects of excavation between adjacent roadways, which is consistent with the simulation results.

Analysis and Research on Traditional Residential Architecture of Jiangxi

[Objective] Through in-depth study of traditional Gan residential buildings, it is found that in China’s traditional culture, nature is more important than architecture. Many people believe that architecture is like a man-made natural object, which can make people return to a feeling of living in nature, and is also a state of ideal life for many residents in China. [Methods] By using the analysis method, it is found that the traditional residential building structure of Ganpai is a bucket structure. The basic unit is the ‘enter’ relationship, which combines the ‘enter’ relationship, the adjustment of column spacing and the reduction of column to form the ‘+ -’ relationship. Through this way, a unique architectural group layout can be formed. [Conclusion] Therefore, we should fully combine traditional materials with modern information means to improve our traditional technology, so as to keep pace with the times, keep pace with the times and keep pace with the times.

Collaborative design of an active learning classroom with high school students and teachers

PurposeThe aim of this study is to understand classroom settings desired by high school students and teachers in an active learning classroom. The research question is whether students and teachers will differ from each other when designing an active learning classroom.Design/methodology/approachIn an effort to design a learning environment for an advanced placement programme, action research methodology was followed by conducting a participatory workshop in a real active learning classroom with future users. Working in isolation from one another, students and teachers designed their own classrooms by forming different learning centres. During the study, two groups, made up of ten high school students and seven teachers, respectively, were asked to arrange the furniture in an active learning classroom. The groups were free to form as many furniture arrangement configurations as they wished and were asked to write about their workshop experiences afterwards. Once they had completed both tasks, their plan layouts were examined.FindingsAll of the plan layouts were found to fall into one of three categories: a traditional layout, a small group layout or a single large group layout. The written texts were also analysed, which revealed different perspectives of each participating group. As students and teachers explore different learning opportunities, they appear to be driven by different kinds of experiences when they endeavour to organize their classrooms.Originality/valueNever before has an active learning classroom been the site for a participatory furniture arrangement workshop that employs teachers and students.

Group Layout Pattern and Outdoor Wind Environment of Enclosed Office Buildings in Hangzhou

This paper presents a study of the effects of wind-induced airflow through the urban built layout pattern using statistical analysis. This study investigates the association between typically enclosed office building layout patterns and the wind environment. First of all, this study establishes an ideal site model of 200 m × 200 m and obtains four typical multi-story enclosed office building group layouts, namely the multi-yard parallel opening, the multi-yard returning shape opening, the overall courtyard parallel opening, and the overall courtyard returning shape opening. Then, the natural ventilation performance of different building morphologies is further evaluated via the computational fluid dynamics (CFD) simulation software Phoenics. This study compares wind speed distribution at an outdoor pedestrian height (1.5 m). Finally, the natural ventilation performance corresponding to the four layout forms is obtained, which showed that the outdoor wind environment of the multi-yard type is more comfortable than the overall courtyard type, and the degree of enclosure of the building group is related to the advantages and disadvantages of the outdoor wind environment. The quantitative relevance between building layout and wind environment is examined, according to which the results of an ameliorated layout proposal are presented and assessed by Phoenics. This research could provide a method to create a livable urban wind environment.
