Deep Foundation Pit Dynamic Design And Information-based Construction Technology

Dynamic design and information-based construction of deep foundation pit engineering is a complicated geotechnical engineering problem and structure design, the project contains relatively complex technology, and comprehensive high, to improve the safety of the project performance, reduce engineering accidents play a key role. It involves design, security, economic, applicable, and so on various aspects. So, for how to design a safe and reliable, economically feasible foundation pit supporting scheme, has become the domestic and foreign, especially the Shared concerns of the foundation pit design personnel.Based on the structural design of deep foundation pit, to solve problems in the information construction in the concrete engineering and construction in the process of the accumulation of experience, this paper adopts theoretical guidance, information collection and engineering application of the method of combining the design and construction of foundation pit and redesign process were compared and analyzed in detailed and comprehensive, and put forward its own views, which provide help for engineering design and practice.This paper first introduces the dynamic design and information-based construction of deep foundation pit engineering necessity and importance, and its connotation, to highlight its important position. And then put forward the whole design and construction process of three parts:the dynamic design of prediction system, monitoring system and information processing system. Three parts complement each other, restrict each other. Finally with an engineering example for them, which reflects the importance and necessity of dynamic design and information construction.The foundation pit supporting to under go two process design and construction. Due to construction stage belongs to the practice of foundation pit supporting, so the construction stage of quality and monitoring delivery information can be timely and effective to the treatment, determines the quality of the whole project. Therefore, the dynamic design of the monitoring system and information processing system is the key content of the supporting part. According to the characteristics of the deep foundation pit engineering, including monitoring system mainly includes: the surveillance program, principles, content, frequency, and the content of the alarm value, etc. Information processing system is mainly to guide and supervise the construction,.for the foundation pit support to provide the corresponding information security.Taking a square foundation pit supporting project as an example, the design of the whole project stage, construction stage and the information processing stage made a comprehensive and detailed in this paper. Ensure the safety of the project smoothly in the end.
