Research And Application Of Foundation Pit Safety Monitoring And Early Warning System

This paper takes the construction foundation pit as the research object, from the datatransmission port and the instrument improvement, monitoring method of innovation,management innovation aspects, the establishment of a complete early warning system offoundation pit monitoring, realize the monitoring data acquisition, real-time transmission,real-time computing, scientific early warning, intelligent alarm, collaborative managementand other functions, the realization of the use of the existing Internet and network informationtechnology to build forecasting system to promote the informationization construction.Combining with idiographic engineering example, it is proved that the system has goodaccuracy and practicability. The main research work is as follows：(1) Developed a complete set of foundation pit risk warning forecast system, shows thesystem architecture, business process and main function.(2) For monitoring carried out innovation, focus on the transformation of the water levelmeasuring instrument, for the first time the osmometer and frequency instrument readingsusing a combination of techniques applied to the foundation pit water level monitoring field,realizes the digital storage level monitoring data, change the past history of human readingdata.(3) The calculation method of monitoring project carried out innovation, developed anew calculation method of the horizontal displacement, namely "virtual section calculation ofhorizontal displacement" method, which is applicable to all shapes of the foundation pit oflarge integrated data processing, effectively improve the work efficiency.(4) Study of the current management situation of the foundation pit, the pit safetymanagement mode innovation, will pit safety management process further flattening, themonitoring of foundation pit supervision idea realizes from passive management to activemanagement, after the rescue to the double shift control in advance, in the.(5) Through the project example, showing the early warning system of the engineeringprocess and the actual results, show that the research is of great application value and theapplication prospect is very wide.
