Abstract

For the safe operation of buildings and engineering structures, and for carrying out restoration work, it is necessary to monitor their technical condition. This paper presents a developed method based on extraction of standing waves from seismoacoustic noise, demonstrating the possibilities of using passive seismic for examining fixity conditions of foundation piles’ and determining its sections characterized by a relative increase in stresses using the Palace of Culture (Norilsk) building as the case study. The standing waves were extracted from the recorded acoustic noise by the accumulation of amplitude spectra of a large number of noise recordings. It is shown that the amplitude spectra can be used to reliably determine the fixity condition of foundation piles. The obtained field experiments results are qualitatively consistent with the results of the computer simulation by the finite element method both for individual piles and for the detected foundation anomalies.

识别永久冻土上支撑结构的桩基可能存在的结构缺陷：诺里尔斯克文化宫案例研究

为了保证建筑物和工程结构的安全运行，以及进行修复工作，有必要对其技术状况进行监测。本文介绍了一种基于从地震声学噪声中提取驻波的方法，以文化宫（诺里尔斯克）建筑为案例，展示了利用被动地震检测基桩固定条件和确定其应力相对增加部分的可能性。通过积累大量噪声记录的振幅频谱，从噪声记录中提取驻波。结果表明，振幅频谱可用于可靠地确定基桩的固定状况。获得的现场实验结果与采用有限元法对单个桩基和检测到的地基异常情况进行计算机模拟的结果在性质上是一致的。
