Foundation pit peripheral stratum settlement micro-motion monitoring system and use method thereof
The invention discloses a foundation pit peripheral stratum settlement micro-motion monitoring system and a use method thereof, and the method comprises the steps: constructing a wave detector triangular array, arranging the wave detector triangular array at the periphery of a foundation pit, and obtaining vibration noise in real time through the wave detector triangular array; the vibration noise is transmitted to the data processing system in real time through a wireless network, the data processing system judges the corresponding relation between the soil depth and the stratum based on the vibration noise, and real-time early warning is carried out by judging whether the change of the corresponding relation exceeds an early warning threshold value or not. Compared with a common land subsidence monitoring system, the system provided by the invention directly monitors the internal condition of the stratum in real time, can early warn and interfere with geological disasters earlier, and avoids chain geological disasters caused by land subsidence; compared with conventional stratum detection methods such as a high-density electrical method, the micro-motion method can achieve 24-hour real-time monitoring, the monitoring cost is lower, the monitoring depth is larger, the occupied area is smaller, and the micro-motion method is more suitable for foundation pit monitoring in urban areas.
本发明公开了一种基坑周边地层沉降微动监测系统及其使用方法，包括：构建检波器三角形阵列并布置在基坑周边，通过检波器三角形阵列实时获得振动噪声；通过无线网络将振动噪声实时传输至数据处理系统，数据处理系统基于振动噪声判断土体深度与地层的对应关系，通过判断对应关系的变化是否超出预警阈值进行实时预警。本发明与常见的地面沉降监测系统相比，直接对地层内部情况进行实时监测，可以更早地对地质灾变进行预警和干涉，避免地面沉降所引发的连锁地质灾害；与高密度电法等常规地层检测方法相比，微动法可以实现24小时实时监测，监测成本更低，监测深度更大，占地面积更小，更适用于城市地区的基坑监测。
