Research On Design Of Supporting Structure For Soft Soil Deep Foundation Excavation

Following the modern city construction and economic development and technology progress, a request higher design of deep foundation pit is put forward, which requires the design theory in the method of deep foundation pit engineering.(1) Based on many years of experience, from the point of the system engineering, the basic design principle of deep excavation in soft soil in the study, optimization design method of soft soil deep foundation pit engineering from four aspects, namely, the three stage, technology, four aspects of economy, optimization of system architecture and environment, phase optimization design calculation and analysis of real-time dynamic inversion;(2)The conceptual design is the key to design of deep foundation pit engineering, this paper focuses on the discussion on a few problems in conceptual design, the parameters, such as pressure, deep foundation pit engineering safety and reliability analysis of choice;(3) Summarizes the supported types and their applicable conditions; to understand the appropriate method of deep foundation pit engineering scheme;(4) Through the calculation of optimal design. This paper discusses several commonly used in supporting structure design method.(5) In combination with the project example, the design method of deep foundation pit in soft soil is mentioned in this paper is its design.
