基于缠绕分布式光纤的多参量同步感知方法
By employing a multi-parameter synchronous sensing method using distributed optical fibers, the problems of high cost, poor adaptability, and cross-sensitivity of traditional monitoring equipment in geotechnical engineering are solved. This method enables synchronous monitoring of temperature, strain, stress, and vibration across the entire domain, providing accurate multi-parameter data support.

Abstract
本申请涉及岩土工程安全监测与工程测试技术领域，提供一种基于缠绕分布式光纤的多参量同步感知方法。多参量同步感知方法包括以下步骤：钻设圆柱形的监测钻孔；将圆柱形传感器植入监测钻孔内，圆柱形传感器的表面固定有沿预设螺旋路径缠绕的分布式光纤，沿预设螺旋路径缠绕的分布式光纤在圆柱形传感器表面形成连续分布的等效三向应变花阵列；在圆柱形传感器与监测钻孔的孔壁之间填充耦合材料；将分布式光纤的端部接入集成光频域反射、布里渊光时域分析与分布式声学传感的多协议分布式光纤解调系统，采集采动过程中圆柱形传感器全域的连续温度、应变与振动数据；解算得到监测钻孔全域的连续温度、三维应变、三维采动应力与振动多参量数据。
