Ground Subsidence Monitoring and Early Warning Solution
Background Introduction
Ground subsidence is a slow‑developing, progressive geological hazard that is widely distributed across alluvial plains, karst regions, and urban built-up areas. Its causes include excessive groundwater extraction, mineral resource mining, engineering construction disturbances, and natural and anthropogenic factors such as karst collapse.
Ground subsidence not only causes deformation and cracking in infrastructure such as roads, bridges, and buildings, but also damages drainage systems, exacerbates urban flooding, and may even lead to difficulties in agricultural irrigation and environmental degradation.
Traditional leveling surveys and manual inspections suffer from long monitoring cycles, limited coverage, and poor real-time performance, making it difficult to achieve dynamic tracking of settlement processes and early warning.
Accordingly, the development of an automated land‑subsidence early‑warning system that integrates deep‑level displacement monitoring, groundwater dynamics sensing, and the continuous surveillance of rainfall and environmental factors—enabling real-time detection of subsidence rates and precursory signs of collapse, coupled with intelligent analysis and interpretation—has become a critical technical safeguard for geological hazard prevention and the safe operation of urban infrastructure.
Solution Overview
This solution is an automated monitoring and early-warning system for land subsidence and karst collapse, based on the Internet of Things, multi-type sensing technologies, and a cloud platform.
The scheme deploys terminal devices—including deep‑level displacement monitoring instruments (stratified settlement gauges), piezometric pressure sensors, water level monitors, automatic rain gauges, and RTU data acquisition units—to perform real-time, continuous monitoring of vertical soil displacements at various depths below the ground surface, pore water pressures, groundwater level fluctuations, and rainfall amounts.
Data is aggregated to a cloud-based monitoring and early-warning platform via wireless communication technologies such as 4G, LoRa, and satellite. The platform incorporates an embedded settlement-rate analysis model and multi-level early-warning rules, automatically detecting abnormal acceleration in subsidence or precursory signs of collapse.
When monitoring data exceed threshold limits, the system promptly issues early warnings via platform pop-up alerts, SMS messages, and on-site audio‑visual alarms, providing scientific decision‑making support to management agencies in natural resources, water conservancy, transportation, and other sectors, and facilitating the early detection of land subsidence hazards, risk assessment, and engineering mitigation measures.
FEATURES OF THE SOLUTION

Real-time monitoring of groundwater dynamics
Automatic rainfall data collection and early warning
Multi-level Early Warning and Visual Analytics

Application Scenario Configuration
From the uppermost stress‑bearing point of the high slope downward, a comprehensive monitoring system is implemented across the slope’s upper, middle, and lower structural layers, with point‑based core measurements that expand to surface‑wide coverage, thereby enabling all‑round, real‑time micro‑deformation monitoring of the entire slope mass.
Display of the Slope-Excavation Housing Safety Monitoring and Early-Warning Platform
The system deploys automated terminal monitoring devices to acquire real-time data on target parameters. An backend data management platform performs intelligent analysis and hazard prediction, automatically issuing early warning and forecast information to relevant personnel. This enables 24-hour, dynamic, all‑round monitoring, allowing continuous oversight—anytime, anywhere—of railway slope deformation, displacement, rockfalls, environmental changes, and structural safety conditions. The system thus provides a scientific basis for natural slope hazard prevention, reinforcement engineering design, and the timely mitigation of safety risks.
