A comprehensive analysis of soft soil foundation pit accident Hui Hu1,2,a, LianSheng Tang1,b，XingLi Lin2,c，and Fei Kuang2,d 1Department of Earth Sciences, Sun Yat-sen University, Guangzhou, 510275, China 2 Department of Mechanics and Civil Engineering, Jinan University, Guangzhou, 510632, China athuhui@jnu.edu.cn, beestls@mail.sysu.edu.cn, c 645438022@qq.com, d kuang_fei@126.com Keywords：Soft foundation；Foundation Pit; Engineering Accident; Anchor; Embedded Depth Abstract: Factors affecting the supporting structure in a soft soil foundation pit are analyzed in this paper.
So the foundation pit is becoming one of the main topics of Geotechnical Engineering in the process of urban construction.
Based on these analyses some qualitative conclusions of engineering accidents may be drawn and may provide a reference for the project’s subsequent processing.

However, the propagation and coalescence mechanism among multi-group cracks is still a puzzle, especially to the engineering rocks in site.

Since early 1950's, the fracture mechanics has brought significant impact on structural integrity assessment in a wide range of industries such as power, transportation, civil and petrochemical industries, especially in nuclear power plant industries.
The application of VR has been vigorously studied in various fields of engineering.

Thin Protective Layers Made out of Special Concretes STANKIEWICZ Natalia1,a *and BOŁTRYK Michał2,b 1,2Bialystok University of Technology, Faculty of Civil and Environmental Engineering, ul.
All concrete and reinforced concrete engineering structures degrade over time when they are exposed to the surrounding environment.

It was developed by more than 50 members who are university researchers, structural designers, and engineers from about twenty damper manufacturing companies.
Such methodology would enable engineers to understand and directly compare control mechanisms, performance ranges, and element interactions of various systems.
