基于植入式分布式光纤传感技术的引黄涵闸混凝土温度监测方法及其应用
Method and application of concrete temperature monitoring for the Yellow River diversion sluice gates based on embedded distributed fiber optic sensing technology
摘要
Abstract
Accurate measurement of temperature variations during the pouring and curing of concrete is of great importance for investigating concrete cracking during the construction of the Yellow River Diversion Project in the Yellow River Basin.Notably,the current construction projects involved in the Yellow River Diversion Project in the Yellow River Basin primarily use thermal imaging methods for surface temperature measurement,making it difficult to obtain real-time overall temperature characteristics of concrete.Therefore,to improve the ecological system of the Yellow River Basin and ensure high-quality development in the region,this research proposes a concrete-temperature monitoring method for the Yellow River Diversion Project based on implantable distributed fiber optic sensing;this method has been successfully used in the Yellow River Diversion Project in Shandong Province.Before concrete is poured,the sensing fiber opthic cable is prelaid on both sides of the involved structural-steel bars,enabling real-time and effective monitoring of the internal temperatures during the pouring and curing of concrete.This method is of great value for ensuring real-time analysis of the temperature of concrete throughout its lifecycle.Experimental results show that the use of implantable distributed fiber optic sensing allows real-time monitoring of temperature changes at various points in concrete and temperature anomalies during curing.Moreover,this method can be used to effectively analyze the overall temperature variation during curing.Using implantable distributed fiber optic sensing to monitor the concrete temperature for the Yellow River Diversion Project is of considerable reference value for similar engineering projects in the Yellow River Basin.关键词
