光纤传感技术应用于深圳市典型天然海绵体效能监测
Effectiveness Monitoring System of Typical Natural Sponges Based on Optical Fiber Sensing Technology in Shenzhen City
摘要
Abstract
At present, in the construction of sponge cities in China, monitoring the effectiveness of natural sponge facilities has always been a problem. This paper relied on the research and development needs of relevant departments in Shenzhen City for sponge city monitoring. Based on the temperature sensitivity of optical fiber sensor, a real-time monitoring model of effective capacity of rainwater collected by natural sponge (poa-soil system) was established with monitored water permeability as a variable parameter, and model system was evaluated by experimental means. Experimental results showed that under various rainstorm, there was a corresponding relationship between water permeability and soil water content. The monitoring error of different rain patterns was within 5% under simulated rainstorm. And optical fiber sensor monitoring system showed superior performance.关键词
