Construction Safety Management

The rapid economic growth in China has promoted the development of all walks of life. The most prominent is the construction industry. The safety management of the project construction during the construction process is very important. If there is a safety problem in construction, it will not only affect the progress of the construction, but serious loss of people and property will occur. Therefore, we should pay more attention to the safety management of the construction. Therefore, we should strengthen the management of safety management and improve the prevention of safety technology. Only under the premise of safety can the progress of the construction work be normal and the requirements of the project before the design are reached. Today we are in the engineering construction safety management problem is analyzed, and the problems of construction safety management is put forward rationalization proposals, prevent the occurrence of all kinds of problems in the engineering construction, to ensure security in project construction.

Deep Foundation Pit

The reasonable selection and optimized design of the deep foundation pit support scheme is directly related to the safety, construction period, and cost of the entire project. Here, based on a large number of theoretical results in many related fields, relevant influencing factors are systematically analyzed, and advanced mathematical algorithms such as neural networks are introduced according to the relevant characteristics of building deep foundation pit support construction. First of all, this paper designs and implements deep foundation pit construction safety risk technology based on wireless communication and BIM technology and analyzes and describes the framework and function of the foundation pit construction safety risk identification system. Secondly, we use neural network algorithms to study the deformation prediction of the foundation pit supporting structure, which can describe the expression method of the above safety knowledge. Finally, the differences and benefits of this method and traditional methods are compared through experiments, which show that this technology can pave the way for the construction of deep foundation pit construction safety risk knowledge.

Emergency Decision

Construction safety accident has occurred frequently and accident death toll has been high. Investigate its reason, mainly in the low level of construction enterprise safety accidents emergency management. Strengthen construction safety emergency management can effectively reduce the life and property losses, and to ensure the sustainable development of construction enterprises. We put forward a construction safety emergency decision support system based on ontology and CBR method. Then we described its work processes and use the foundation pit engineering as an example to explain the knowledge representation and the ontology similarity case retrieve matching method. Finally, we give the method to realize the system so as to reach the purpose that improved the building enterprise emergency management capacity effectively.

The Impact

Based on the impact of deep foundation pit excavation to the adjacent history style construction, FLAC3D was adopted to establish the excavation and supporting calculation model of a pit in Tianjin. The excavation deformation was analyzed, and the contact slip effect of the supporting structure and soil was considered. The results of study are as follows. (1) The pit has been dig to the third layer, and the values calculated are consistent with the monitored ones by comparing simulation values and measured results on B1 section. (2) Digging to the bottom of the pit, we can predict the biggest horizontal displacement of soil is 34.6 mm, and the value is 11.2mm in the history style construction. Therefore, the results of the study can play a guiding role in the engineering construction safety.

Research Studies

Recent years have seen a great concern on the construction safety of the deep foundation pit with complicated geological conditions due to an increasing number of accidents. However, there are not, currently, sufficient research studies on the safety analysis of the deep foundation pit in water-rich soft soils. As a result, dynamic predictions of the safety risk during the whole construction process are inadequate due to the lack of research studies. Therefore, this paper presents an approach for the construction safety of the deep foundation pit in water-rich soft soils, which combines the building information modeling (BIM), the finite element analysis (FEA), and the finite difference method (FDM). By using BIM technology, the author attempts to establish a 3D information model and a bracing structure model. Based on the application programming interface and the C# language, the data conversion from BIM-ANSYS-FLAC3D is realized. The author then attempts to analyze the ground surface settlement and horizontal displacement during the excavation of the deep foundation pit through FLAC3D, and the purpose of which is to identify potential safety hazards so that reasonable control measures can be taken. The approach presented in this article has been validated in the Project of Qinhuai River Ship Lock. Since the excavation and the after-construction stages of this project have been completed smoothly, this approach has been proved valid and applicable.
