[Abstract]:In this paper, a complete foundation pit monitoring and warning system is established from the aspects of data transmission port and instrument transformation, monitoring method innovation and management innovation, so as to realize the monitoring data collection and real-time transmission of foundation pit. The functions of real-time calculation, scientific early warning, intelligent alarm and cooperative management are used to promote information construction. The system has good accuracy and practicability. The main research work is as follows:. 1) A complete early warning system of foundation pit danger is developed, and the structure, business process and main functions of the system are constructed. The monitoring instrument has been innovated, the water level measuring instrument has been reformed, the technique of combining the osmotic pressure meter and frequency reading meter has been applied to the field of water level monitoring of foundation pit for the first time, and the digital storage of water level monitoring data has been realized. Changed the past history of manual reading of data. In this paper, the calculation method of monitoring project is innovated, and a new calculation method of horizontal displacement is developed, that is, "virtual section calculation horizontal displacement method", which realizes large scale data integration processing of foundation pit suitable for all shapes. Effectively improve the efficiency of the work. 4) the present situation of foundation pit management is studied, the safety management mode of foundation pit is innovated, the flow of foundation pit safety management is further flattened, and the monitoring and supervision of foundation pit is changed from passive management to active management, and from emergency to advance. A double shift in control. 5) the practical effect of the early warning system studied in this paper is verified by an engineering example, and it is proved that the research result has great application value, and the application prospect is very broad.
