预埋光纤监测法在变电站预应力管桩负摩阻力监测中的应用

Application of pre-embedded optical fiber monitoring in negative friction monitoring of prestressed piles in substations

旨在探究欠固结地区变电站负摩阻力分布规律,采用预埋光纤监测法对某变电站工程中管桩状态进行实时精准监测。结果显示:监测数据与理论结果相符,验证了该方法的有效性;同时,受施工干扰影响,部分桩基负摩阻力监测值偏大。研究为变电站软土区域桩基负摩阻力的计算与监测提供了参考,对类似工程中的桩基监测具有借鉴意义。

This study explores the negative friction resistance distribution in under consolidated substation areas using pre-embedded optical fiber monitoring to precisely track pile conditions.The monitoring data aligns with the theory,validating the method.Some piles exhibited higher resistance due to construction interference.This research offers a reference for negative friction resistance calculation and monitoring in soft soil substation pile foundations,informing similar projects.
