Research on limited bearing capacity detection method of large erection equipment operation site

摘要

To enhance the survival capability and fast reaction capability of missile weapon system, the research on choosing launching site during the process of missile erection has been carried out. In this paper, the bearing load of launching site is analyzed in missile erecting process, and the equation of limiting bearing capacity is deduced according to K. Terzaghi suggesting equation. Combining with explicit reliability analyzing method, the sensitivity analysis of factors which influence the bearing capacity has been executed, and the detection method has been researched for partial factors which influence bearing capacity obviously. Finally, the general conceptual design of evaluating bearing capacity and choosing launching site have been provided based on blocking design thought.
