Slope real-time bearing capacity limit monitoring method and system

Abstract

The invention discloses a slope real-time bearing capacity limit monitoring method. The method comprises the following steps: (1) detecting and investigating a site environment, a landform, a site structure and historical conditions; (2) determining a monitoring scheme according to a detection result, wherein the monitoring scheme comprises mechanical property indexes, the number of monitoring points, arrangement positions and frequencies; (3) establishing a monitoring mathematical model; (4) arranging sensors at monitoring points, and collecting monitoring data, and uploading the monitoring data to a cloud server; (5) receiving and storing, by the cloud server, the monitoring data and analyzing the monitoring data in real time by combining the monitoring mathematical model to obtain a real-time safety coefficient FOSins; and (6) sending different levels of early warning signals to the monitoring terminal according to the real-time safety factor FOSins value. The invention further discloses a slope real-time bearing capacity limit monitoring system. According to the method and system, site material characteristics and actual force stability are considered, the site real-time safetylevel is evaluated at any time in combination with the cloud server technology, personnel safety escape time is reserved, and personnel property loss is 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 slope. Background technique [0002] The existing monitoring method for mountains and slopes 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 req...

Problems solved by technology

[0004] (2) The limit values ​​of SLS monitoring parameters are defined based on engineering experience or rules of thumb, and these limit values ​​cannot reflect the stress state of the structure;

[0005] (3) The characteristics of materials are not considered in the SLS monitoring method

[0006] This shows that above-mentioned existing a kind of SLS monitoring method still has inconvenience and defective, and urgently needs to be further improved
