Dynamic back analysis calculation and fusion algorithm and intelligent monitoring system

Abstract

The invention provides a dynamic back analysis calculation and fusion algorithm and an intelligent monitoring system. The algorithm comprises the following steps of monitoring the deep horizontal displacement of an underground diaphragm wall in real time by using an omnidirectional real-time displacement tube, collecting the acceleration and corner data of the wall body at each measuring point in the underground diaphragm wall, and obtaining the horizontal displacement of each point of the wall body relative to the top end by using an STRDAL algorithm, enabling the monitoring platform to collect various data measured by the omnidirectional real-time displacement pipe, solving and exporting a horizontal displacement curve, fitting the deep horizontal displacement curve into a unary multiple equation through drawing software, and performing inversion analysis by utilizing the dynamic soil pressure to obtain the soil pressure at any depth behind the wall. Not only can real-time continuous monitoring be realized, the use is flexible and convenient, the measurement precision is high, but also better economical efficiency, higher safety and more accurate predictability are realized, and dynamic back analysis calculation and fusion algorithm has important significance for scientific research in foundation pit engineering.

Description

technical field [0001] The invention relates to an intelligent monitoring system based on dynamic back analysis calculation and fusion algorithm and belongs to the technical field of foundation pit monitoring. Background technique [0002] In recent years, buildings and structures such as subway stations and interval tunnels have flourished. In order to meet the construction requirements of these buildings and structures, it is first necessary to increase the depth of foundation pit excavation and expand the scale of foundation pit excavation. Therefore, ultra-deep foundation pits continue to emerge, and the problems of deep foundation pits continue to increase, and it has gradually become a rock in modern urban construction. One of the main research contents of soil engineering. Nowadays, ultra-deep foundation pits such as shield working wells are not uncommon, which have very strict requirements on the real-time performance and accuracy of foundation pit monitoring.

Problems solved by technology

Traditional measurement uses manual data collection, the efficiency of data collection and transmission is low, the time interval of data collection is long, and the cumulative error continues to increase

Once the accumulated error exceeds the threshold, it will not only affect the construction of the working well structure, but also interfere with the construction period of subsequent projects.

In this way, it is impossible to grasp the dynamic information of the foundation pit in real time, resulting in the inability to take corresponding measures to deal with it at the first time when there is an abnormality in the foundation pit, delaying the timing of dealing with the problem, and easily causing construction safety accidents
