Researchers always face a problem of how to better analyze and understand the BIM academic hot spots and trends. This paper proposes a method based on data mining technology to better analyze the BIM academic hot spots and trends, which uses SATI, Ucinet and Cite Space software to process bibliographic information. By mining and analyzing data from different forms and perspectives, the hidden laws of data information can be discovered, assisting relevant personnels to understand the academic hot spots and trends of BIM. In the paper, the method is described from three aspects of data extraction and processing, BIM academic hot spot analysis, and BIM academic trend analysis. In order to test the practicability of the method, the method is applied to the literature data analysis of BIM academic conference. Results show that the method is able to make different software complementary. And conclusions are made that current BIM researches mainly focus on data transformation and automatic modeling based on IFC Standard, BIM and PC building, etc., and that the future research focuses of BIM will turn to the academic development trend of basic research.

With the development of informatization in the construction industry, the BIM technology has been rapidly popularized and implemented due to its unique advantages. However, as an evolving technology, BIM still faces many obstacles in the practical application. Among them, the legal issues have already attracted many attentions of researchers and practitioners, which, however, is lacking of corresponding research results in China. Thus, this paper adopts the method of literature review to analyze the legal issues existed in the BIM application in foreign countries from three aspects of ownership, responsibility and contract relationship, which will certainly lay a good foundation for the future research and judicial practice in this field in China.

Based on the existing problems in project practice, such as the difficulty in controlling the quality of rebar splicing by grout-filled coupling sleeve, the modular self-insulated concrete shear wall structure system was innovatively proposed.Through the pseudo-static test in-plane of 9 pieces of shear wall and the pseudo-static test of 2 coupling beams, the cooperative performance of multiple spliced shear wall and the seismic performance of assembled self-insulated shear wall and coupling beam were studied, the calculation formula of flexural capacity of self-insulated shear wall and coupling beam was verified.The test results indicated that the multiple spliced shear wall has good cooperative performance. Under the medium axial pressure ratio, the self-insulated shear wall has good seismic performance. The flexural capacity and displacement ductility ratio of the self-insulated beam are similar to the solid beam.At the same time, some suggestions on improving the ductility of self-insulated shear wall under high axial pressure ratio are put forward.The related results can provide the basis for the application of the structure system.

This paper establishes models of the VRV & fresh air conditioning system and the primary return air conditioning system by using the software of Airpak, to simulate the temperature field and velocity field distribution of indoor air flow under two conditions in summer, and then to evaluate indoor thermal comfort and air quality by adopting the indexes like PMV-PPD and air age. Results show that both the wind speed of two schemes can meet the requirements of comfort air conditioning, without obvious sense of blowing for people. Compared with the VRV & fresh air conditioning system, the primary return air conditioning system has smaller air flow disturbance, smaller temperature fluctuation in respiratory area, and better indoor air quality with timely delivered fresh air.

the soft rock tunnel of shallow buried Puma water rock is located at the underground interchange section of Xiangli high speed Hujiaoxia which is under construction. The lithology of the surrounding rock is mainly composed of limestone splint rock and slate rock intercalated limestone, which is difficult to construct and high in risk. It is the main control project of soft rock tunnel construction. On the basis of establishing reasonable engineering geological model, the section of typical soft rock tunnel of SC-1 type is selected as the research object, and the numerical simulation of tunnel construction schemes such as reserved core soil, single side tunnel and double side wall tunnel with FLAC3D software is carried out. Through the comparison and analysis of the stress and deformation of surrounding rock, it is proved that the double-side wall guide pit method is used in shallow underground excavation. Tunnel construction is safer. However, the construction cost of two-side guide wall construction method is higher, so the construction cost factor should be considered at the same time to meet the requirements of construction safety and surface settlement, which has higher numerical requirements for the selection of construction method. According to the requirements of numerical simulation, on-site monitoring, project cost budget and surface settlement, this paper considers that the construction scheme of double-side guide wall is suitable for this project, and can also control the surface settlement of shallow buried section by strengthening the supporting parameters of one-sided guide wall construction method. This study can be used for reference in the selection of similar tunnel construction methods.
