Example Embodiment

[0045] The present invention provides a real-time bearing capacity limit monitoring method of a retaining wall. The monitoring method (referred to as ULS monitoring method) is an innovative monitoring method that uses real-time monitoring data and cloud analysis to calculate the risk index Ri of the retaining wall . The monitoring method takes into account that the structural strength and load change with time, so a new comprehensive quantitative index (risk index Ri) is established to assess the real-time safety level of the structure. The specific real-time bearing capacity limit monitoring method is introduced in detail as follows.

[0046] Reference attached figure 1 As shown, the method for monitoring the real-time bearing capacity limit of the retaining wall in this embodiment includes the following steps:

[0047] (1) Detect and investigate the site environment, topography, site structure and the history of the monitoring area of ​​the retaining wall to be monitored;

Abstract

The invention discloses a retaining wall real-time bearing capacity limit monitoring method. The retaining wall real-time bearing capacity limit monitoring method comprises the steps that (1), the site environment, the topography and landforms, the site structure and historical conditions are detected and investigated; (2), a monitoring scheme comprising the mechanical performance index, the monitoring point number, the arranging position and the frequency is determined according to a detection result; (3), a monitoring mathematical model is established; (4), sensors are arranged at the monitoring points, and monitored data are collected and uploaded to a cloud server; (5), the cloud server receives and stores the monitored data and analyzes the monitored data in real time by combining themonitoring mathematical model, and a real-time safety coefficient FOSins and a risk index Ri are obtained; and (6), different grades of early warning signals are sent to a monitoring terminal according to the magnitude of the risk index Ri value. The invention further discloses a retaining wall real-time bearing capacity limit monitoring system. According to the retaining wall real-time bearing capacity limit monitoring method, the site material characteristics and the actual force stability performance are taken into account, real-time safety level assessment is conducted on the site at anytime by combining a cloud server technology, the personnel safety escape time is reserved, and personnel property losses are avoided.

Description

technical field [0001] The invention relates to the technical field of geotechnical and structural engineering, in particular to a method and system for monitoring the limit of the real-time bearing capacity of a retaining wall. Background technique [0002] The existing monitoring method for retaining walls is to use the serviceable limit state (SLS) monitoring method, which has been widely used in geotechnical and structural engineering. Deformation, inclination, settlement, displacement, etc. are key monitoring parameters in different national codes (Technical Code for Building Slope Engineering GB50330-2013, Chinese Code for Building Deformation Measurement JGJ8-2016, and related British codes and American codes). In general, the parameter limit values ​​of these SLS monitoring methods are determined according to engineering experience or rules of thumb. In addition, these limit values ​​vary in different national and regional practices. Also, the SLS monitoring method...
